Given this expand on hover feature added in bug 1930201 is still behind a pref (`sidebar.expandOnHover`), we decided to land that with a few remaining issues to investigate: Due to window transparency with system themes, we were unable to exactly match the sidebar background color with the color of the toolbar when expand on hover is enabled and the sidebar is absolutely positioned. We should investigate a better solution for the background color of the `sidebar-wrapper` when expand on hover is enabled when a system theme is applied if possible. There's also an issue when resizing the sidebar panel and sidebar launcher when the sidebar is positioned on the right. There's a bit of a visual glitch happening as long as you're dragging the splitters. This does not occur when the sidebar is positioned to the left.

We should investigate a better solution for the background color of the `sidebar-wrapper` when expand on hover is enabled when a system theme is applied if possible. There's also a glitchy-ness when hovering right on the edge of the launcher as the mouseover / mouseout event listeners keep getting called in a loop until you move the mouse. There's also an issue when resizing the sidebar panel and sidebar launcher when the sidebar is positioned on the right.
