Buttons disappear when a sidebar opened

[leic4u]

When I open the sidebar of the Monica extension, all elements of the edit page respond correctly except the save and return buttons.

but the other elements response correctly, except the Save and Back buttons only.

Actually, this is not my fault. I use positon: fixed; bottom: 0; right: 0 to make the FooterToolBar fix in the bottom of the screen.

The following documentation is about positon: fixed, excerpted from https://developer.mozilla.org/en-US/docs/Web/CSS/position

In my opinion, the browser should change the width of viewport to make sure that elements are not covered by the sidebar extensions.

I also install Monica in Chrome, and it has the same behavior with Edge, it looks like a Chromium issue. Fortunately, I found that using position: sticky can also fix the element in the bottom, so I "fix" this issue in
