ClickData working after PC Restart


I´ve come across this and wanted to let you all know, maybe someone understand the underlying issue.
I have a Callback with an clickData Input, the clickData didn´t work suddenly (hover,select worked). I couldnt troubleshoot the issue and desperately restarted my PC, after that it worked again. I did not change the code. The restart was the sole reason for it to work. Can this be an issue caused by the browser, it cant be the Code!? Weird if you ask me.
