[marissa-cleroux]

colcount-* classes caused Edge and Chrome to hang - urgent issue, seems to be a result of using column-count, started with new Edge/Chrome release on December 5th.

Hello, what version of CDTS are you experiencing this issue with? Thanks

[marissa-cleroux]

4.0.46

We have removed any reference to the class from our code base as a fix.

We are trying to understand and narrow down the issue. Where did you remove the colcount classes from?

Also, can you check if there are other places where those classes are there? because the CDTS footer has those classes currently present.

I removed it from the static fall back templates, just to be safe. It doesn't seem to be an issue with the dynamic template thus far. We were also making use of the class in some of our code base (which we have removed and replaced with CSS grid). The column-count property doesn't seem to always cause a page to hang, but just in certain cases. I am trying to narrow it down the cases. To see the issue, you must have a version >108.
