Can not use multiple val selectors with strings

[kpdecker]

Attempting to do something like

:has(:root > :first-child:val("string")) :has(:root > :first-child:val("string"))

Causes an invalid json string error.

Ran this with some additional logging and it appears that the parser is trying to evaluate this as a JSON string:

"string")) :has(:root > :first-child:val("string"

Can work around this issue by performing another evaluation loop in the javascript space.

nice find, I'll take a look shortly.
