Reproduces on `master` and found while testing the search fix PR here. Devin does not think it's caused by his PR.
I don't have concrete repro steps and there are no errors in the JS console but I've attached a GIF of the channel bolding in the LHS. Takes quite a while to get it to repro so sorry about having to watch the GIF until the very end!
1. Create some test messages in two channels
2. Search for individual words that you know will return results, search for a string in quotes, search for "in:~channel"
3. Change channels a couple of times and search again for "in:~channel"
The channel name I typed in the search input box for "in:~channel" becomes bolded in the LHS channels list
The channel name does not become bolded
