## Change
- Header: Use the "channel list undefined" instead of "active channel url undefined" to determine if the button should be "pending".
- App: restore the use of `activeChannelClaim` instead of `activeChannelId`. In the existing design, the latter is never cleared is some situations, so the former is more accurate as it takes the current channel list into account. We might want to hide (not export) `activeChannelId` to avoid this mis-use again.
## Why
The playing URI was being cleared every time we leave the File Page, I believe to prevent the floating from continue playing outside of the File Page.
## Approach
Close FileRenderMobile by checking playingUri/primaryURI instead.
For the case of livestreams, just display it.
- Marked optional props properly.
- Re-ordered to make it easier to differentiate "props used in jsx" vs. "from redux".
Separated the commit to make the upcoming diffs easier to read.
Code-splits the module into "dnd.js", reducing the ui.js bundle size. This module is only needed when viewing lists.
## Room for improvement
`ClaimList` can probably improve further by only using the dnd components in "edit" mode.
## Implementation notes
- The modules are not default exports, so the additional chaining to `React.lazy` was required.
- Experimenting with using an Object to store the import so that a single "prettier-ignore" can be used to make it not wrap.
- The FlowFixMe came from the original code. It is unclear why it is needed to resolve the module, but Haffa mentioned it's something related to .flowconfig.
## Ticket
852 Markdown inline images in comments don't work for any channel level
## Change
The prior commit simplified the props from individual comment fields to just 1 `Comment` object, but there was a typo in the parameter where it should be `channel_url` instead of `author_uri`.
- The previous 2MB was a CDN limit (more of a mistake). That has been increased to a far greater number, so we're setting a more reasonable 5MB limit.
- The previous code checks/shows the "size exceeded" message after the file has been uploaded ... in the `catch` block. This will not work since the CDN now allows a 5MB file.
- Fixed by checking the size before actually uploading.
## Issue
When pressing "Done", it will call the upload function, which usually results in a "please select a file" error, or the file being uploaded if a file was selected prior to switching to "Use Url".
