Timeline filter bar disappears if no event found

[Kapcash]

Version

6.1.0

Browser and OS info

Vivaldi 5.1 / macOS 11.6

Steps to reproduce

1. Open Timeline tab in Vue Devtools
2. Go on any timeline that has events shown already
3. Filter by anything not corresponding to an event (should result in "No events found" message)

What is expected?

The filter bar should still be visible so we can remove the filter input.

What is actually happening?

The filter bar is hidden and not accessible in any way.

No workaround found

Once disappeared, there is no way to make the filter bar come back. Changing tabs or timeline doesn't change anything.

Possible solution:

I guess that's because the filter bar is hidden when there is no inputs yet in the timeline.
But the condition to hide it should be that there is no events to show AND that the filter input is empty.

Otherwise we just can't clear the filter input we put.
