Window.setWindowBackgroundColor was crashing with "Cannot read properties of undefined (reading 'replace')" when called with an undefined color. Unsure why it happens but now skip the update instead of crashing.

Fix #8517

Window.setWindowBackgroundColor was crashing with
"Cannot read properties of undefined (reading 'replace')" when called
with an undefined color, which happened in popped-out editor windows
when switching to a theme that doesn't define its toolbar background
color. Now skip the update instead of crashing.
