When a filterable is used in an el-select, then if you click on the arrow, the select will open, but if you then click again on the arrow, it does not close.If you click on the field, everything works fine

In addition, it seems that when you click outside to close the popover, it takes two clicks on the arrow to open it back up again.

// Your fix does seem to fix that issue as well.
