Bug description

In Nextcloud 34.0.1, the Files app popover/dropdown is positioned incorrectly when the UI language is set to Persian (RTL). The same action works correctly in English (LTR), so this appears to be an RTL-specific frontend positioning bug.

Actual result:
The popover is rendered in the upper-right area and overlaps the right navigation sidebar / wrong boundary area.

Environment:

• Nextcloud: 34.0.1
• UI language: Persian (RTL)
• In English (LTR): works correctly
• Affects Files app / share popover / dropdown positioning

Steps to reproduce

1.1. Set Nextcloud UI language to Persian.
2. Open Files.
3. Open a file details/share popover or dropdown.
4. Observe that the menu opens in the wrong position, overlapping the right sidebar instead of appearing next to the clicked control.
2.
3.

Expected behavior

The popover should open aligned with its trigger and remain inside the viewport, respecting RTL layout.

Additional info

This looks like a popover placement / boundary / RTL positioning issue rather than a general responsive layout problem. Screenshot attached: `Screenshot 2026-07-07 173944.png`

Start by reproducing the issue in the Files app with the UI language set to Persian, then inspect the share popover or dropdown positioning relative to its trigger and the right sidebar. Done means the popover stays aligned with its trigger and inside the viewport in RTL while preserving the existing English behavior.
