Grid doesn't animate properly in Firefox (works in Chrome and Safari)

Hi, I have a animation/grid issue that only appears in Firefox. In Chrome and Safari, the animation occurs as expected.

Here is my site Read-Only: LINK /resume > “Expand details”

Thanks in advance :nerd_face:

This has been racking my mind for the past day and I’ve still got nothing. Luckily, Firefox’s CSS grid inspector helps visualize the problem.

I might’ve gotten a little bit closer. I changed the date cells to use white-space: nowrap instead of making them span across the whole row, and it seems half of the problem has been solved?? I’m even more confused now.
