HTML bug: `.is-collapsed` class is removed in 'filter' menu in `base` file

Describe the bug
When a .base file is open, opening the filter menu incorrectly removes the .is-collapsed class from the bases-toolbar-section-header element in the upper part of the view.

This may cause unintended layout shifts or styling issues.

Steps to Reproduce

  1. Open any .base file.
  2. Click to open the filter menu in the toolbar.
  3. Inspect the HTML of the upper bases-toolbar-section-header element.

Expected Behavior
The bases-toolbar-section-header element should retain the .is-collapsed class when the filter menu is opened.

Actual Behavior
The .is-collapsed class is missing from the bases-toolbar-section-header element.
