887731 - Unable to copy text from style editor or debugger after switching docshells

Status: RESOLVED WORKSFORME

(Core :: DOM: Navigation, defect)

Description

[Mike Ratcliffe [:miker] [:mratcliffe] [:mikeratcliffe]]

Switching the toolbox from the bottom of the browser window to the right, or undocking it, switches docshells and intermittently stops the "Copy" context menu item from being enabled when text is selected.

STR:
1. Open the style editor.
2. Select some text and right-click, "Copy" will be available.
3. Dock the toolbox to the side of the browser window or undock it using the buttons at the top right of the toolbox.
4. Select some text and then right-click to bring up the context menu, "Copy" will be available (you may need to switch docshells more than once).

Hmm.  The browser is what decides to enable or not that context menu item.  Why does it decide to not enable it?

I may be misremembering but I think Gijs looked into something like this.

If we're being very liberal, maybe bug 873518 qualifies as 'something like this'. :-)

No idea why this would happen, offhand, but a good point to start would be this code in browser.js:

Tried following the reproduction steps and I am unable to reproduce (I can always copy the text). I'm going to mark this worksforme but if someone has new reproduction steps then we can re-open.
