314606 - invisible iframe with focused input shows cursor somewhere in original page

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[J.P.Klippel]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051031 Firefox/1.6a1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051031 Firefox/1.6a1

Setting an iframe with a focussed input field to style:none in the document body causes the input cursor of the iframe to be displayed somewhere in the original page. It remains there even if the tab or the application is changed. It vanishes as soon as another page is viewed with/in the test-window. Navigating back in the history to the testcase does not show the cursor until the site is (manually) reloaded.

Reproducible: Always

Steps to Reproduce:
1. open testcase


Actual Results:  
blinking cursor somewhere on the screen (not necessary in the firefox-window)

Expected Results:  
No cursor at all.

I found this bug while working on a testcase for bug #314526. As a consequence this testcase is similar to the testcase of bug #314526. 
(Adding a comment there, too)

Attachment: reduced testcase of bug 314526 - exposing this bug

Added testcase of bug 314526 as it exposes the bug too. Simply click on this testcase to show the problem. This way one does not have to download the attachments 201502 + 201503 to reproduce the bug.

Duplicate of bug 121704?

Might be related to bug #121704 but I wouldn't call it a dupe. 

Note: in the testcase in bug #121704 the cursor remains in the page blinking but if you change the tabs or even the application the cursor is gone.
In this bug it's different. The cursor/carret remains visible even if you switch to another application.

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
