Subject: [PATCH] fix: prevent inline toolbar from closing when clicking on
 form controls inside it

When clicking on a form control (e.g. <select> or <input>) inside the
Inline Toolbar popover, the selection is lost, which triggers a
selectionchange event. The selectionChanged handler was unconditionally
closing the Inline Toolbar when there is no selection range, even if
the user is interacting with a form control inside the toolbar.

Fix: check if the active element is inside the Inline Toolbar before
closing it. If the user is focused on a form control inside the toolbar,
keep it open.

Fixes #2985
