Odd parsing of image extensions in text blocks

It was reported that there is an odd parsing of image extensions when they happen in regular text blocks like this:

- "Mike Gif?raw=trueford" instead of "Mike Gifford" on [this page](https://chaoss.community/practitioner-guide-demonstrating-org-value/)
- "both original MD and screenshotted PNG?raw=true format" instead of both original MD and screenshotted PNG format" on [this page](https://chaoss.community/kb/metric-release-issue-template/)

I've narrowed it down to the plugin that was built for us from the LF _years_ ago, and have been digging into the code to see where this might be originating from. This only happens when the content of the WP page is pulled dynamically from a GitHub markdown file, not when something is built in WP itself.

Dropping this issue for when I have more time to look at this, as I've already spent a few hours digging and diagnosing. :blush:
