No scrolling side panel Tiles

Both on Desktop Safari, Chrome and iOs, wonderful side panel Tiles unfortunately won’t scroll. Ive asked @eddi89 on his repo, but maybe it is not Tiles related and others are experiencing related issues?

I only noticed after adding a 4th row (in the main grid), creating the need to scroll.

I have no other side panels to see if they scroll or not.

Hassio 65.4 (though on the previous versions this was also happening)
latest Tiles version, but no-scroll was also there before.

Hope anyone has ideas how to change this.

Cheers and thx,
