Repro is with GA Zui v1.0.1.

A community user reported the following in a Slack message and provided the attached video. I've reproduced the same behavior on Windows and also confirmed that it does not seem to repro on macOS. 🤔 In their own words:

Right clicking on the domain name may result in the context menu not appearing. A work around is to select the ‘inspector’ or clicking the corner of the table.
This was was on a Windows machine : )
