Cannot resize column in covering test popup

[v3.17.0.2]

The columns in popup seems resizable but nothing happens when I try to resize them.

Thanks for sharing this problem. This looks like it may be a recent development ... it's happening on my end too.

We'll take a look at this and see if we can get it fixed :)
