Failed assertion: line 206 pos 12: '_overlay != null': is not true.

Since updating our version to 2.2.0 one of our tests is failing:

'package:flutter/src/widgets/overlay.dart': Failed assertion: line 206 pos 12: '_overlay != null':
is not true.

When the exception was thrown, this was the stack:
#2      OverlayEntry.remove (package:flutter/src/widgets/overlay.dart:206:12)
#3      _ElTooltipState.dispose.<anonymous closure> (package:el_tooltip/el_tooltip.dart:124:53)

This issue does not exist/happen when downgrading our version to 2.0.0 again.
