light-dark-overrides.css The window background is white due to no accentcolor in the lightweight theme. It can't be changed to transparent when there is no compositor (Win 7 in classic / basic theme), or else dragging and focus become broken. So instead just show the normal titlebar in that case, and override the window color as transparent when the compositor is available. 3806

sidebar.css To ensure the button doesn't expand unnecessarily for short labels, the spacer should significantly out-flex the button. 3425
spotlight.css Whether this is actually still required is not totally clear, but better to be safe than sorry: For some reason SubDialog browser sizing can result in scrollbars, so just hide the horizontal scrollbar that would have then required vertical scrollbar. This should be okay as we wrap content for this fixed width dialog unless the window is actually narrow and really does need horizontal scrollbars. 1914

webRTC-indicator.css On macOS, for windows with small enough dimensions, we seem to get vertical scrollbars on the body, even when the contents initially fit the window. We sidestep this by making sure we never display scrollbars. 10705
