When the named grid area starts with a number, for eg, 1-logo, the grid visual helpers don’t work anymore. Not sure if named areas can’t start with a number, if so, appropriate error message must be displayed.
Moreover, the grid doesn’t obey named area and just automatically position all the content within the grid container.
PG does throw an error message if I try using special characters… likewise, it should also throw the same error message when the name starts-with a number… I spent hours and finally figured out that PG allowed the invalid grid area name, hence the visual grid layout was broken.
