Bug description

^ this dialoge is unusable. I can't enter the password nor can I click a button.

Calling OC.PasswordConfirmation.requirePasswordConfirmation() after a fresh page load is usable. The confirmation dialogue only doesn't work when a modal is open.

Steps to reproduce

1. Log into Nextcloud as admin
2. Wait x hours for the password confirmation to kick in (don't know the exact time)
3. Open the user management
4. Create a new user

Expected behavior

Password confirmation dialogue opens and I can use it

possibly related to the v5.4.0 update of nextcloud-vue, which brought the focus trap for modals: nextcloud-libraries/nextcloud-vue#2654

[ChristophWurst]

then it's indeed the identical issue that we also had/have with Mail and v5.4 nextcloud/mail#7034 (review)

[PVince81]

there were additional fixes for modal focus trap which we might need to backport: nextcloud-libraries/nextcloud-vue#2955 nextcloud-libraries/nextcloud-vue#3020

[PVince81]

the backports were merged, need to retry with stable5 of nextcloud-vue to see if the issue is fixed

[PVince81]

I've tested with stable5 with the fixes merged, but the problem persists

I suspect this is due to having two modals on top of each other, maybe confusing the focus trap

[PVince81]

yeah... I see that the focus is still on the modal behind and not in the new modal... you can still tab onto the fields...

[PVince81]

I tried upgrading the lib to 6.9.4 but it didn't help.

I'll try to build a test case directly in nextcloud-vue, this way we can test and debug it there

[PVince81]

I suspect that we need to detect when the current modal is not focused any more and then pause the focus trap until we return to that modal. We currently don't have the semantics to know which modal is currently on top.

[PVince81]

Hmm, I created an example in nextcloud-libraries/nextcloud-vue#3087 and the focus trap works fine there.
Either there are more changes on master / nc vue 6.0.0 or it's the way how the dialog is invoked that is different.

Next up:

• test if bug exists on Bump @nextcloud/vue to 6.0.0-beta.4 and related #33516

[PVince81]

I forgot we already had this ticket.

Anyway, I made a new one moving forward: #33675
