Hey Sebastian,
I tried to reproduce this issue with the latest version of Firefox Nightly 80.0a1 (2020-07-09), beta 79.0b5 and release 78.0.1 with the "button.disabled = true" but the button "Hello, Dave" was disabled/grayed out on all 3 for me and even Chrome.

Can you test the issue while in Safe Mode. You can find helpful info here : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .

Also a fresh new profile could help. You can find more about creating a new profile here : https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile .

If possible, you can test this issue on the nightly build as well. Download the build from : https://www.mozilla.org/en-US/firefox/nightly/all/ .

but the button "Hello, Dave" was disabled/grayed out on all 3 for me and even Chrome.

This is what I observed as well. I didn't report that this wasn't disabled but that the disabled button is still focused.

I tried it on firefox 78 and I can still observe the reported behavior. To clarify the reported behavior:
On firefox it logs:
"BUTTON"
"blurred"
"BUTTON"

On chrome it logs:
"BUTTON"
"blurred"
"blurred"
"BODY"`
