Fixed Autolinking affected by short code to emoji replacements

When I paste a link from eBay it will not unfurl.

Example of typical eBay URL:

Code: 
https://www.ebay.com/itm/KTM-690-Duke-Front-Headlight-Assembly-2012-2018/333068937357?hash=item4d8c74a88d:g:Ti8AAOSwaEZcYgpA:rk:1:pf:0

After saving the post, the link will show like this with the emoji added at the end:

195719

If I remove everything after the ? in the URL like this example:

Code: 
https://www.ebay.com/itm/KTM-690-Duke-Front-Fender-2012-2018/333068911386

the unfurl functions correctly:

195720
 
When posting the following text, XenForo turns emoji shortcodes like :flag_pf: into an emoji (and thus breaks the URL):

https://www.example.org/?foo=:flag_pf:&bar=1

There is no issue if I manually enclose the URL in "URL" bb codes like this (instead of letting XenForo auto-link it):

[URL]https://www.example.org/?foo=:flag_pf:&bar=1[/URL]
https://www.example.org/?foo=:flag_pf:&bar=1

It seems like XenForo first replaces emoji shortcodes and then auto-links URLs. It should work the other way around.

You can see the real non-reduced eBay URL where this has happened here: https://www.computerbase.de/forum/threads/lte-richtfunkantenne-telekom-hybrid.1856800/post-22329347

Thanks for moving my post. Please note that the issue I reported seems unrelated to unfurling (we have not enabled URL unfurling).
 
Thank you for reporting this issue. It has now been resolved and we are aiming to include it in a future XF release (2.1.1).

Change log:
Use a slightly more strict regex when detecting shortcodes in order to not necessarily attempt to replace embedded shortcodes, especially those inside URLs.

Any changes made as a result of this issue being resolved may not be rolled out here until later.
