Collapsing and expanding already-loaded epics has no click feedback
When an epic tree has been loaded, expanding and collapsing child epics sometimes either doesn't respond or is delayed with no feedback.
Reproduced on gitlab.com
On gitlab.com, the epic in question is &170. Once the initial GraphQL queries have been fired (showing the loading widget), there is a delay, with no UX feedback, that sometimes takes too long. Re-expanding/collapsing (clicking twice) usually helps.
To reproduce:
- Go to &170
- Expand and collapse all the child epics (no need to do so for the 'grandchild' epics)
- Click - there is a delay (sometimes enough to violate Akscyn's Law, sometimes not).
I reproduced this on both Firefox and Chrome, but I did find that it was slightly intermittent.
