Sizzle, expando, $.clone(), ie6-8

[linhao87@…]

Sizzle will add a variable: expando = ( "sizcache" + Math.random() ).replace( ".", "" ).

When i use $.clone(), the 'sizcache' would record in html tags, i need to clear them by RegExp.

Sorry for my poor english.

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: ​http://jsfiddle.net/FrKyN/. Open the link and click to "Fork" (in the top menu) to get started.

I don't know if we'll want to fix this, but it is real. It affects .html() as well.

It's been like this forever though, so although it might affect serialized html it doesn't have any really bad effects. Trying to remove those properties would make the slowest browsers even slower.

True, but negligibly so. It's just more removeAttributeing in ​cloneFixAttributes and a tweak to ​rinlinejQuery.

But it would add some size that might be better relegated to a plugin.

So I think I've got this fixed, but the unit test was a bit evasive. Can you confirm against the new edge build?
