If I use the cross-post feature to copy the post elsewhere, the form is populated just fine but then I have to search for the target community at the bottom of the form. As soon as I select the target community, the whole rest of the form clears. If another field is re-populated, the target community field clears. So only one field at a time can be populated.

Tested with Tor Browser.
