Bug Summary

I had another thread opened but it was closed because it was a Lepton related issue, but as I stated below, Lepton itself doesn't have this issue. Here's the other thread: https://github.com/Floorp-Projects/Floorp/issues/1196

When you select "Show Sidebar over website content", but also set the sidebars to show up on the right, the sidebars seem to still expand to the right, outside of the browser.

I also tested this in Firefox by installing Lepton UI to my Firefox setup and it works there with no problems. So this could be a Floorp specific Lepton configuration.

Reproduction Steps

1. Select "Move sidebar to the right" from the sidebar header
2. Enable "Automatically hide Sidebar" from Lepton Settings
3. Enable "Show Sidebar over website content"

Expected Behavior

When you hover over the hidden sidebar on the right, it should expand to the left, making the whole thing visible

Actual Behavior

The sidebar expands to the right, nothing happens

Browser Version

Additional Context

I tried different sidebars other than Sidebery like history, bookmarks etc. but the result is the same. I also tried toggling Browser Manager Sidebar but that didn't change anything
