## 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:
Fixes 4411 `"SelectChannel=New" doesn't show all fields on re-entry`
## Code Changes:
`selectChannel`: Correct the value of `addingChannel` in the constructor based on the given props.
(1) This reverts commit 8641a3ee1c.
(2) Fix floating-player misalignment due to YT badge in mobile by hiding the badge.
At first, the suggestion to truncate the left URI to keep the entire thing single-lined was implemented, but during testing, I realized that the YT badge will take up the entire width anyway (especially on other languages). The URI is more important than the badge, and truncating both of them would be ugly.
Given the preference to not have 2 lines for this, we'll just hide the badge for the mobile case.
For the Channel Page case, let's make it single-line through "4454: URL / top claims overlap" instead. We'll keep this commit/PR limited to fixing the YT badge.
## Issue
Fixes 4524 `[mobile] in channel search not available`
## Changes
There are currently 3 wunderbars: (1) header (2) channel list (3) downloaded list.
The additional `wrapperStyle` in the header made it hard to find a solution that works for all 3, so I split 2 and 3 into `wunderbar__input--inline`.
## Issue:
Currently, the checkbox grayed-out state is only correctly updated when changing from "no-file" to "file selected". If you have selected a video file and later changed to a text file, the checkbox doesn't gray out.
## Code Changes:
`fileVid` wasn't being updated for the case of non-videos; now it does.
