the credential plugins context menu for a domin gets hidden when it should still be shown due to its context.

probable regression from https://github.com/jenkinsci/jenkins/pull/10245 (works in 2.504.1 fails in 2.508)

Steps to reproduce

login to https://ci.jenkins.io/
navigate to https://ci.jenkins.io/me/credentials/
Hover over "credentials" in the header to show the initial domain store ("User") popup (note other domain stores are available in folders etc).
hover in "User" until "Add Domain" pops up. (the icon is missing but this happens in 2.504 also)
Move the mouse into "Add Domain"
Wait 10 seconds

Expected results

The "User" popup for the domain is still shown as this is the context for the "Add Domain" popup. (this is the case prior to https://github.com/jenkinsci/jenkins/pull/10245)

Actual results

After a few seconds the "User" popup disappears leaving a missing context
