Correctly reposition items of ExpandBar during DPI change

When using the monitor-specific rescaling functionality on Windows,
moving a shell between monitors with different zoom levels (no matter
which zoom levels they are), the images, expand items and texts are not
drawn at correct coordinates.

This change fixes the behavior to perform an appropriate layout update
of the ExpandBar.
