Description Mark Macdonald

2013-06-26 10:57:51 EDT

Chrome 29.0.1547.0 (dev channel)

1. Open a .js file that contains block comment with a URL in it.
(For example, most Orion source files have http://eclipse.org in their license comment).
2. Use the mouse to select some text in the editor.
3. Press Ctrl.
4. Move the mouse slightly. This will cause the URL to turn into a clickable hyperlink.

However, the Orion editor immediately loses focus (your selection turns grey, and you get the default cursor instead of the I-beam). At this point, you cannot use the keyboard to interact with the editor anymore. The document.activeElement shows <body>. To get focus back, you need to move the mouse around, which causes the hyperlink to go away.

I often hit this bug this when trying to use Ctrl+X/Ctrl+C/Ctrl+V. If I don't keep the mouse perfectly still between pressing Ctrl and 'c', the hyperlink appears, the editor loses focus, and the action I was trying to perform does not happen.

Does not happen in Firefox.

Actually, I can reproduce this on documents without hyperlinks, even on a plain text file. It is a side effect of holding Ctrl while moving the mouse cursor.

1. Open a file.
2. Select some text
3. Hold Ctrl, then move the mouse slightly.
4. Focus lost

I cannot reproduce this with Chrome Version 28.0.1500.70 beta-m.  I will try the dev channel.

The Canary channel also had this bug last time I checked.

The focus is lost when the contentEditable flag is reset to show links. Setting tabIndex to zero fixes this problem on Chrome 29. The same problem happens on IE, but setting the tabIndex does not help.  On IE, I restore focus when the link mode is disabled.

This bug is not solved for me.

Happens in canary Chrome, Firefox 29, nightly Firefox.

Hyperlinks do not works.

Cursor only returns in chrome after releasing Ctrl key.

In firefox I have to release the page to get the cursor back.

I have removed the codemirror plugin and still see the problem in HEAD of master.
