11168	undo fills in stuff which never was existing there - in the changeset comment	aseerel4c26	Don-vip	"0. have previous uploads (so you have a upload comment history)
1. set upload.comment.max-age = 0 (more info: see #9438), so the comment field is empty by default
2. edit some data
3. press the upload button (upload window appears)
4. hit ctrl+z. 

Expected: nothing, since I did not enter text in this field before, so there should be nothing to ""undo"". 

Actual: the last changeset comment appears.

Note: this also happens if you enter any text and then Ctrl+Z and hold the keys, because you want to undo everything you've entered. Expected is that you get an empty field. Actual is that you land in some old comment.

In JOSM v. 8103 (although I guess that never was different). System: Linux, Java version: 1.8"	defect	closed	trivial	19.04	Core	latest	fixed	undo upload comment
