While typing a text in an input field, every use of the AltGr modifier (ie. AltGr+7 = [ on German layout) triggers a "blur" event on the input field and the whole document.
This can lead to issues with websites, since the user actually didn't leave the input and is continuously typing.
Testcase: Enter in the interactive console:
document.addEventListener("focus", function(){ console.log("focus "+new Date().getMilliseconds()) })
document.addEventListener("blur", function(){ console.log("blur "+new Date().getMilliseconds()) })
document.addEventListener("keydown", function(){ console.log("keydown "+new Date().getMilliseconds()) })
I get this when hitting the AltGr key:
"blur 358"
"focus 363"
"keydown 369"

While typing a text in an input field, every use of the AltGr modifier (ie. AltGr+Q = @ on German layout) triggers a "blur" event on the input field and the whole document.
This can lead to issues with websites, since the user actually didn't leave the input and is continuously typing.
Testcase: Enter in the interactive console:
document.addEventListener("focus", function(){ console.log("focus "+new Date().getMilliseconds()) })
document.addEventListener("blur", function(){ console.log("blur "+new Date().getMilliseconds()) })
document.addEventListener("keydown", function(){ console.log("keydown "+new Date().getMilliseconds()) })
For a normal key (like Q) I only get the keydown event.
When hitting the AltGr key, I get this:
"blur 358"
"focus 363"
"keydown 369"
This happens also for the Super and Alt keys. But while the Alt key doesn't work as modifier (Alt+Q does not give @), the AltGr key does not work for operating system shortcuts. Its use is purely as keyboard modifier.
