Event details popover widget should focus the "Join" or "Edit..." buttons when available, instead of selecting the description / location's text
This is a trivial papercut issue, but probably a nice UX enhancement to do nonetheless.
In the month/week/sidebar view, when you click an event that has description/detail/notes, or "location", the GtkPopover that shows up pre-selects whatever details text there might be:
It would be better to tell GTK to not select those, and instead pre-focus:
- The first "Join" button, when available (it will show up when a meeting is detected)
- The "Edit" button, when there are no Join button(s) and when the Edit button is available (i.e. the event is not read-only; see #977)
...that way it wouldn't look weird with the text preselected, and it would allow activating the most relevant action/button simply by pressing the Enter
key, which might be convenient and good for accessibility.
