Button/Input field for new tasks randomly disappears until reload

[verymilan]

Description

I could not properly pin down on which action causes this glitch, but i think it is related to the detail modal - every now and then, all of the list views love the button for adding new tasks until the page is being refreshed. To my suprise, i wasn't able to find such an issue here, maybe it's a Firefox issue? Or maybe the favorite list?

I could not intentionly reproduce but it happens multiple times per day. Due to that fact, i have checked "no" for the demo site, but it means nothing until i know how to reproduce.

Vikunja Frontend Version

0.20.5

Vikunja API Version

v0.20.4

Browser and version

Firefox 112.0.1

Can you reproduce the bug on the Vikunja demo site?

No

This looks like the permission is lost and thus Vikunja assumes read only. I think we might get away with that by caching the permission in local state (I think we do that already?)

We need to be able to reproduce the problem to fix it, so please share when you notice how it happens. Maybe after the tab got inactive and then active again?

Hmm now i was idle in Favorites for a while, marked a task as done, then went to a list that ... had the button missing in each view... i went back to Favorites, was distracted for a moment, went back to a different list ... and now its resolved again.. curious.

Edit: added a task in kanban view, clicked on it for setting priority and already see in the background that the buttons vanished - and they remain hidden as i close the modal

From what you're describing it feels like this could be related to opening a read only list (like the favorites).

Can you reproduce thisbwith the steps you've described on try?
