Internals: Windows hidden with HiddenFramesRegular (but NOT HiddenFramesForResize) preserve their SizeContents, so restoring a auto-resize window after it's been hidden by tabs won't reset its size for a frame. Arguable. Let's see how it goes. (Followup to b48e295bddbf965d7382ec5578ed05d2fe601114)

@ -51,6 +51,7 @@ Other Changes:
- Added ImGuiWindowFlags_UnsavedDocument window flag to append '*' to title without altering
the ID, as a convenience to avoid using the ### operator.
- Window: Contents size is preserved while a window collapsed. Fix auto-resizing window losing their size for one frame when uncollapsed.
- Window: Contents size is preserved while a window contents is hidden (unless it is hidden for resizing purpose).
- Window: Resizing windows from edge is now enabled by default (io.ConfigWindowsResizeFromEdges=true). Note that
it only works _if_ the back-end sets ImGuiBackendFlags_HasMouseCursors, which the standard back-end do.
- Window: Added io.ConfigWindowsMoveFromTitleBarOnly option. Still is ignored by window with no title bars (often popups).
