What version are you seeing this on? What OS? Does it repro in a clean profile?

I tested 57 beta on macOS, and can't reproduce.

Version 58.0a1
Build ID 20171009100134
for now.
It is reproducible on Windows10 1706 x64, LinuxMint 18.2 x64, manjaro linux 17(17.0.5) x64, with fresh new profile.

56.0 with browser.photon.structure.enabled;true have this issue as well.

It's not only 'Paste'...

STR:
1. Type some characters in text field.
2. Open menu, hit Ctrl+Z, type some characters, select all, click 'Cut'.

AR:
Nothing is cut, edit controls are disabled.

ER:
Selected text is cut, edit controls are enabled.

There is no any message in browser/web console.
If I set breakpoint at
chrome://global/content/globalOverlay.js - function goDoCommand (#89)
it is working(stopped at the breakpoint) when normal case, but it is not working when problematic case...
