"Manage experiments" tool takes time to close

[frode-aarstad]

How to reproduce:
Add a some experiments by running esmda etc
Open the "Manage experiments" tool
Close it by clicking the X.
Observe that it takes some time to close

Might not be observable on a fast mac but surely observable on a slower desktop RHL machine

Check if this is still the case after we reverted combined, if not, we can close it.
