585463 - When (re-)creating nsTextControlFrame from onfocus handler, the caret doesn't show

Status: RESOLVED DUPLICATE of bug 536421

(Core :: Layout: Form Controls, defect)

Description

[Mounir Lamouri (:mounir)]

Some attribute changes in nsHTMLInputElement requires frame re-creation (see  nsHTMLInputElement::GetAttributeChangeHint). If you do one of this change in a onfocus handler and this change require a (re-)creation of nsTextContralFrame, the text field does not seem focused because the caret isn't showed.

STEP TO REPRODUCE:
1. Open: data:text/html,<input type='button' onfocus='this.type="text";'>
2. Click on the button

ACTUAL RESULT:
- the text field doesn't seem focused (the caret doesn't show)

EXPECTED RESULT:
- the text field should look focused (the caret should be showed)

NOTES:
- the text field is actually focused (document.activeElement returns the input element)
- this bug is present in 3.6.8 so it doesn't come from Ehsan changes in nsTextControlFrame
