(MOBILE) Clicking One Filter Apprears to Open Dropdown Under Another Filter in marketplace

Description:

On mobile screen sizes, the filter dropdowns (e.g., Sort By, All prices, All statuses) in the Marketplace / Apps page appear incorrectly.
The dropdown menu is rendered in an unintended position, making the UI look broken and affecting usability on smaller screens.

This issue is not observed on desktop screen sizes.

Steps to reproduce:

1. Open Rocket.Chat in a mobile browser or resize the browser window to a mobile viewport (≤ 768px width).
2. Navigate to Marketplace and use the filters in Installed or Premium page
3. Click on any filter dropdown (e.g., Sort by).
4. Observe the dropdown menu positioning.

Expected behavior:

• The filter dropdown should:
  • Open aligned with the trigger element
  • Stay within the viewport
  • Be fully usable on mobile screens without overlapping or floating incorrectly

Actual behavior:

Start by reproducing the issue on the Marketplace / Apps page at a viewport of 768px or less, using the Installed or Premium filters. Locate the filter dropdown entry point and inspect how its menu is positioned relative to the trigger. Done means each filter opens aligned with its trigger, remains within the viewport, and is usable without overlapping another filter.
