Test case to reproduce the issue

What steps will reproduce the problem?
(1) load the attached testcase
(2)
(3)

What is the expected result?
In the top two grids, all <span>s should be 30px wide (the width of one column).
In the last grid, all <span>s should be 65px wide (the width of two columns with a 5px grid gap in-between).

What happens instead?
All abs.pos. boxes (pink color) are 5px too short.
This how Firefox renders this case, which seems correct per the CSS Grid spec.
