Jira macro duplicates content when in-place editor

Some days ago I noticed a strange behavior with the Jira Macro continuosly adding content when changing the macro properties during page editing.

I reported it ( Loading... ) but wanted to know if anyone else is facing it.

Macro 10.2.1 on XWiki 16.10.9

Thx for reporting (not seen it, but I rarely use the wysiwyg editor)
