Fix Disabled component infinite loop for a elements

[david-szabo97]

Description

This PR here: #24397 not long ago, introduced a change the Disabled Component to disable hyperlink focusing. The change causes "infinite loop". Since we add tabindex to a elements, but then we remove it immediately.

This PR fixes it by adding an else-if to avoid the inifinite loop.

How has this been tested?

1. Open Block Editor
2. Open inserter (top-left plus button with black background)
3. Click on Patterns
4. Keep pressing tab

Before: (Notice a element keeps changing)
