Same issue here.

I had the same issue.

For some it's solved with this added in userChrome.css

#sidebar-splitter{ display:none !important }

I had an expanded area on hover so I had to add the following to solve the issue.

#sidebar-box:hover,
#sidebar-box:focus-within {
  min-width: var(--sidebar-visible-width) !important;
  max-width: var(--sidebar-visible-width) !important;

 Hope this helps.
