Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

recording_20230507_104049_1.mp4

The Filter icon doesn't disappear when scrolling down, it also overlaps with the "Make changes permanent" and "Revert changes" buttons and can be clicked when over those buttons, but i forgot to record that.

A specific URL where the issue occurs.

https://www.reddit.com

Steps to Reproduce

1. Using mobile uBO, go to a webpage with tons of entries on the firewall (like Reddit);
2. Open uBO's popup and scroll down on the firewall section;

Expected behavior

The filter widget should "slide under" the power button's "box", just like everything else that scrolls.

Actual behavior

The filter widget stays on top of the power button's "box" and overlaps with other buttons.

uBO version

1.49.2

Browser name and version

Firefox 112

Operating System and version

Fixed.

Side note: clicking a second time should hide the widget - not obvious where to click to hide it now.
