pasting text into the forums editor always pastes as size=1 ?

[madscijr]

Does anyone else notice this quirk, where if you paste text into the forums editor, it always shows up size=1 ? 

For example if I copy a single word or phrase "my text" and paste it in here, I get:

Code: (Select All)

[.size=1]my text[./size]

(Note I added a "." so the editor doesn't think they're actual formatting. Even in a code block it seems to interpret those as actual formatting tags.)

It really becomes a problem when pasting in larger text that has formatting. 
For example text copied from here:
   

pasted into the editor looks like this:
   

and dropping down to code view, we have this mess:
   

which wouldn't be so bad, but why the [.size=1] ? 

Is there any way to stop the editor from doing that? 

Any help appreciated!
