1436309 - resistFingerprinting prevents browser shortcuts to work in some pages

Status: RESOLVED DUPLICATE of bug 1433592

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Markus Jaritz [:designakt] (UX)]

Attachment: Copy_Paste_Bug_fingerprinting.gif

How to reproduced:
- create new profile

- create a google doc, or go to github
- select some text
- press "Strg" + "c" to copy that text

- enable "resistFingerprinting"
- repeat previous steps

expected result: 
I still can copy text.

actual result:
"Strg" will be ignored, and "c" is interpreted.
(as typing c in google doc, and as creating a new issue on github)

(see attachment for recording of that behaviour on google doc)

Observed on all current channels of Firefox, on Windows 10.

Same symptoms here on Linux: the ctrl key is swallowed so ctrl+c to copy ends up typing a c, ctrl+z to undo types a z etc. I've seen this in google docs.I can toggle the behavior by enabling/disabling the privacy.resistFingerprinting;true pref in about:config.
