Fix incorrect close of a status popover when clicking Expand inside it

Closes #1157

See merge request pleroma/pleroma-fe!1514

basically Vue (3 in particular?) will make changes to DOM before this event
listener is called, and if the target is displayed using v-if, it will not
be part of the DOM at that time, and contains() will return false. so it
goes to call hidePopover() which caused this bug.
