Steps to reproduce
This on 7.5 Alloy Web forms.
If you try to make an external link to Google for example and that URL contains a ID query parameter, it will be converted into a "internal" link if the content ID exists on the CMS site. If it doesn't exist it will not update the link property with the new value.
Steps to reproduce:
1. Find a page that has a URL property
2. Create an external link to http://www.google.com?id=4
Observed: Link created to the page with ID 4 in the CMS instead of to Google.
2 (alt): Create an external link to http://www.google.com?id=1000000
Observed: No link created at all.
