Incorrect behavior of FancyZones when toggling taskbar

[Jaytn]

Environment

Windows build number: [Version 10.0.18363.720]
PowerToys version: v0:19.0
PowerToy module for which you are reporting the bug (if applicable): FancyZones

Steps to reproduce

• Create and apply layout
• Hide taskbar
• Drag a window to a zone bordering the taskbar
• Launch Zones Editor (to reapply layout)
• Drag a window to a zone bordering the taskbar
• Unhide taskbar
• (repeat 3-5)

Expected behavior

This was the behavior prior to v0.19.0

• Stretch layout to fill available screen (in-/excluding where taskbar would be or not, respectively) immediately after toggling taskbar
• Zones Preview accurately represent layout

Actual behavior

• Keeps previous stretching when toggling taskbar.
  Will only re-stretch when re-applying layout after switching to a different one.
• Area where taskbar would be is blank in zones preview, no matter if the layout includes the area (see above) or not.

Screenshots

Window not stretched into freed area after hiding taskbar (layout not reapplied)

Window stretched under taskbar (layout not reapplied after unhiding taskbar)

Area under taskbar blank in preview - layout was reapplied, so window would stretch correctly, but preview is not showing this

I'm sorry, I noticed that while I was writing the issue, someone else, posted it already.
