Cannot change tag color (web app, Windows laptop)

[steve-biggs-fox]

Steps to Reproduce

1. Create new task and tag it with a new tag, e.g. "Test #Test". Tag gets created with default color (pale pinky purple)
2. Click the 3 dots on the tag in the tag section in the left pane and select settings
3. Select theme color or primary color. Color selection popup appears. Pick a color. Click OK. Color appears to be selected in tag settings.
4. Switch back to today list. Color of the tag in today list is not updated. On returning to the tag settings, color has reverted to default.

Thank you very much for opening up this issue! I am currently a bit overwhelmed by the many requests that arrive each week, so please forgive me, if I fail to respond personally. I am still very likely to at least skim read your request and I'll probably try to fix all (real) bugs if possible and I will likely review every single PR being made (please, give me a heads up if you intent to do so) and I will try to work on popular requests (please upvote via thumbs up on the original issue) whenever possible, but trying to respond to every single issue over the last years has been kind of draining and I need to adjust my approach for this project to remain fun for me and to make any progress with actually coding new stuff. Thanks for your understanding!

Update: Affects Firefox Version 134.0.2, but does not affect Google Chrome Version 132.0.6834.84. Workaround for Firefox users - sync Firefox to Dropbox, open Chrome, sync Chrome from Dropbox (keep remote), update color in Chrome, sync color from Chrome, close Chrome, update Firefox sync, color in firefox should be updated now.
