## Issue
Users are annoyed with the constant reset of the 'channel' setting in the Publish page.
## Changes
1. Revert the previous attempt in ff7b4092. The `usePersistedState` method is bad, as it will clash with the Redux value.
2. Implemented the persistence in Redux -- requires "https://github.com/lbryio/lbry-redux/pull/347".
## Issue
The sidebar text stuck in English despite already translated.
I'm guessing the i18n macro only ran once for the global object.
## Change
Run the macro on the label when passing it to the `Button`.
## Issue
The previous commit was over-doing the manual syncing, causing other usages like the Repost Modal to always reset to a different channel.
## Fix
Only do the manual syncing when the channel does not exist.
At this point, we could also just take `channel[0]` as the new value.
## Issue
Fixes `4544 Channel-creation in "Tip|Support" Modal shouldn't submit LBC immediately`
## Changes
`Form` seems to have already tried to stop the propagation of `onSubmit`, so I'm not sure why it was still propagated.
Fix by using the same method used in the `CommentCreate`, which is simply to check for `CHANNEL_NEW` as the current selection.
## Issue
Fixes `4621 Can't create Comments if you recently deleted a channel`
The `channel` that the parent passes in is from a persisted state. If the channel has been deleted, `<select>` will automatically resolve to another selectable value. However, `onChange` will not be called for this scenario, so we now have a mismatch.
## Changes
- Manually check if the value has been auto-resolved and report it to the parent.
- An extra `setTimeout` was needed. It seems like `onChannelChange` needs to be called after the first `useEffect` of the parent, otherwise the call has no effect.
## Issue
In the `Autoplay` case, if the `WaitUntilOnPage` has already opened the gates previously, the next video's Related will be loaded regardless of scroll position.
## Changes
Add a `lastUpdateDate` prop to `WaitUntilOnPage` to allow the parent to reset the gating state.
I don't really like the `lastUpdateDate` prop since it's purpose is not intuitive. Is there a standard way to do a "one-time trigger" from the parent?
This allows `RecommendedContent` to render the Card but with an empty list, so that the area isn't totally blank while waiting for `WaitUntilOnPage` to debounce.
There are cases where `WaitUntilOnPage` will incorrectly render, such as at the beginning if the upper components hasn't expanded to full size, so `WaitUntilOnPage` would be briefly visible.
Added a 300ms debounce to fix this, which would also improve scrolling performance a bit by doing less. Hopefully 300ms is enough for the upper components to inflate to full size.
## Issue:
Fixes 4549 `Mature content + navigating to URLs directly`
_If a user navigates to mature content directly, we currently show the page even if mature content setting is not enabled. With our recent mature content verification setting, we should hide the page until the user turns it on - we can prompt directly on the file page._
## Changes:
1. Show basic info of the claim like URL and Title, so that user knows which page is being blocked.
2. Initially, I had 2 "boxes" -- one for the title and another for the message. It felt a bit messy, so `FileTitle` was augmented to house everything in one box.
## Issue
When navigating back and forth between a File and Channel page, the back-action will be laggy (no response) if the channel contains a lot of comments and is in the midst of resolving them.
## Changes
The "full" fix would be to batch-load comments, as this would improve the performance of fetching both Channel and File comments. For now, this commit focuses on the Back action problem only.
Skip fetching comments by not mounting 'ChannelDiscussion' until the tab is selected. I couldn't find anything in the Reach UI documentation on how to not render inactive `TabPanel`s, so I used the straight-forward state method.
