<input type="color"> error on macOS Catalina 10.15.5

System color picker start only two times then you must refresh page.

< input id=“front” type=“color” oninput=“generateQRCode()” >
< input id=“back” type=“color” oninput=“generateQRCode()” >

When you click on “front” then on “back” you can’t open color picker for “front” again.

In other browsers is working well.

Thanks for the report.
I’m able to reproduce the issue and I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1649741 so the appropriate team can have a look at it
