           Summary: Deleting password at bottom of large page causing 100%
                    CPU
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: sbaronda at emergeinc.com


When deleting all the text in the password field either by command-delete or command-a delete, it causes the system to use 100% CPU for about 15 seconds.

I have only noticed this for password type field and when they are at the bottom of a large page.

Deleting works fine when you do one character at a time but fails when you try to select all and then delete.

I know that my HTML doesn't verify, but looking at the verification report it doesn't seem like it would make the system use 100% CPU

This might or might not be related to 79815.  HIs/Her version didn't hang when I did command-delete, so I figured a new bug report was needed.  It could also be because his version is a lot smaller than mine.
