Bug 4499 – 16 byte leak in HTMLGenericFormElementImpl::resize

• Component: Forms
• Status: RESOLVED FIXED

[John Sullivan]

I saw a couple of instance of this leak after the following steps:
1. launch Safari to an empty page
2. visit bugzilla.opendarwin.org
3. search for all open WebKit bugs

I clicked around a few times also, so these steps might not be enough (also, 'leaks' does not give fully 
repeatable results). This smells like a localized (thus easy to fix) problem to me.

Leak: 0x1dc5e610  size=16
