- After selecting Cut/Copy from context menu option the following error is thrown into browser console: “document.execCommand(‘cut’/‘copy’) was denied because it was not called from inside a short running user-generated event handler. WordEditor.box4.dll1.js:364:52”.
It feels like the
document.execCommand(‘cut’/‘copy’) is put in async callbacks, e.g. setTimeout, and we currently don't support propagate user-activation across async callbacks (see bug 1185052).
