[WK2] Support findPlugin through file extension when a mimetype is not null

• Component: Plug-ins
• Status: RESOLVED WONTFIX

[Sangho Kim]

I think it's good for users if users mistake to write invalid mimetypes, WebKit finds plugin through file extensions.
Now, WebKit finds plugin through file extensions when a mimetype is only null.
How do you think about that?

Needs [WK2] prefix. I will retitle the bug.

It'd be good to elaborate a bit here. Why is this change needed?

It’s generally not a good idea to disregard an explicitly provided MIME type.

I agree, but I don't feel too strongly about it.

However, if we don't have any evidence of real world web sites that are fixed by this change I don't think we should make it.
