Gridstack.js: "cellHeight=8rem" breaks during resize in 2.0.0

[71GA]

I migrated to Gridstack 2.0.0 and I noticed that relative units do not work for "cellHeight" anymore. Here is the minimal working example: https://jsitor.com/YYbJFy7UY

To reproduce... First run with line cellHeight: "8rem" comented and everything seems to work. But then uncomment it. You will see that positioning / placeholder don't work if line is not commented out.

here's the default example with cellHeight: "8rem" set which shows the issue when resizing (renders ok initially).
