130542 - XUL <textbox> has focus but not caret

Status: NEW

(Core :: XUL, defect)

If I click the text box, enter some text, then select some of the text within
the green border and hit some keys on the keyboard, more text is entered into
the text box, even though it no longer has focus.

On first visit to the page, the border of the text box is light - that is,
non-focused.  When you click it, it's border goes darker, and the caret flashes.
 When you select some text elsewhere (eg in the green border), the border of the
text box stays dark, but the caret disappears.  Surely, if the text box is
supposed to keep focus even though you've selected elsewhere (not what I'd
expect), the caret should stay there?

Reproducible: Always
Steps to Reproduce:
1.  Click the text box, and enter some text
2.  Highlight the words "This label has a green border"
3.  Type a few letters on your keyboard - note the letters go into the text box

Actual Results:  The letters appear in the text box

Expected Results:  Nothing - some text had focus, and the text box didn't have a
caret, so no text should have appeared.

Note the the textbox keeps the focus outline....

This is correct behavior in XUL, I believe (except for the bit with the caret).

Over to the right component -- this has nothing to do with HTML form controls,
resummarizing to focus on the caret issue.

duplicate of bug 130418?

I've found that when this bug occurs, any oninput event handlers on the textbox
are ignored.  This makes the bug more serious, since it breaks being able to get
input as it is entered.
