stack trace

It seems that we sometimes try to hide the popover when it's not being shown.

Steps to reproduce:

1. Collect some layout timeline records with and without stack traces
2. Select layout timeline panel
3. Select a record
4. Use keyboard up/down arrows to quickly switch the selected record

It seems that this assertion failure happens when either:

a) switching from row with stack trace (popover open) to a row with no stack trace
b) switching from row with stack trace (popover not open) to a row with stack trace

The latter case is triggered by pressing up-up quickly enough to change selections before the slight delay in popover appearing.
