I clicked once.
Based on testing at https://www.mediawiki.org/wiki/User_talk:Quiddity_(WMF)#A_barnstar_for_you.21 the steps to reproduce might be:
- Go to Quiddity's talk page on mw.org
- Open Wikilove. Choose a barnstar from the drop-down menu.
- Press Esc to cancel. (Go do something else, e.g., scroll down the page or open a link in another tab.) (If you skip this step, then Wikilove works normally.)
- Open Wikilove again. Choose a barnstar from the drop-down menu.
- Press Esc to cancel. (Go do something else, e.g., scroll down the page or open a link in another tab.)
- Open Wikilove a third time. Choose a barnstar (maybe needs to be the same as the first one?) from the drop-down menu.
- Fill in the box.
- Send Wikilove.
- See two identical barnstars on the page.
- Refresh the page.
- See three identical barnstars on the page.
I've only tested this in Flow.
