Reduced test case for gap rendering on a subgrid

Subgrids are rendered without gaps, if the parent grid uses percentage values for gaps, and the subgrid doesn't have its own gaps explicitly defined.

This is the case, when I want a subgrid to span multiple columns of the parent grid, but not all of them. If the parent grid has its column gap defined as a percentage, that will be relative to the width of the parent grid. For the subgrid to match the layout of the parent grid, it must implicitly use the same gaps.

I attached a reduced test case.

I tested this in Safari 16.5.1 (Webkit 605.1.15) as well as Safari 16.6 (615.3.12)
