The search bar on the left collapsible panel is not clickable

[Poiuytreza]

Not really troublesome, just putting it here

I'm on Windows 10, firefox 82.0.3
When the window width is small enough ( -> half the screen or less ) so that the top bar becomes the collapsible left panel,
That bottom part with "Manga" isn't clickable
The textbox neither

The search button works:
- If the textbox is empty, puts focus on textbox ( and then i can write inside it )
- If the textbox has text, performs the search

Hope i gave enough details
( The usual top bar works )
