1916763 - copy button is disabled after a tab is drag to a different window

Status: NEW

(Core :: DOM: Core & HTML, defect)

Description

[Sean Feng [:sefeng]]

This is from https://old.reddit.com/r/firefox/comments/1f79xlh/firefox_v1300_should_be_officially_out_tomorrow/ll6zn0r/ and I can reproduce it

Basically the STR is

• Have two windows open
• Use middle button to click a link to open a new tab where it has content that can be copied. Verify the 'copy' is enabled in context menu.
• Drag this tab to the other window

The 'copy' button starts to become 'disabled' in the context menu.

I can reproduce the issue on Nightly132.0a1 Windows11, but not on Ubuntu22.04.

Bug 1681712 did not fix the following case:

1. Start Firefox
2. Ctrl+N to open a new window
3. Move the new window so that the tabbar of the previous window is visible
4. Open https://ftp.mozilla.org/pub/firefox/nightly/ in a new tab on the new window
5. Drag and drop the new tab to the tabbar of the previous window
6. Focus the previous window
7. Select text, and right mouse click, observe Copy menuitem

NOTE:

1. After the bug occurs, switch between tabs or switch between windows will fix the issue.
2. If the tab is dropped after switching to the previous window by dragging over the taskbutton before dropping the tab, the problem does not occur.
