1463710 - Persisted grid overlay color is sometimes not applied

Status: NEW

Since bug 1401847 the grid inspector remembers the grid overlay color (per domain).
However in certain cases this color isn't re-applied correctly.

Steps:
- open https://lynnandtonic.com/
- open the grid inspector
- display the grid overlay on the body.home grid
- use the color picker to change the color of the overlay to something else
- reload the page --> the grid overlay is automatically re-displayed after the page has been reloaded and the color is persisted and applied too. This is good
- now, hard-reload the page and check again. For me (on Windows) I use ctrl+F5. On mac it seems that it requires more refreshes. But eventually, at some stage you should see the following

--> the grid overlay is automatically re-displayed, but its color is the default purple one, not the color you chose. However, the color of the color-swatch icon is the correct one, and toggling the grid off and on again fixes it.

So it seems like the persistence works, but in some cases, the grid inspector just doesn't send the persisted color to the overlay when showing it.
