Extra parameters being added to frontmatter urls

[DeaJae]

Searched for similiar expanations and not found very much specific to this. Thought i'd try and report it as its baffling me to annoyance.
Hopefully this makes sense and not being an idiot and missing something i should have spotted weeks ago.

Describe the bug
When adding an image to a post, or loading an image from library, it displays fine in editor, but the preview panel adds HTML parameters which aren't visible in browser or terminal output, a example from editing the HTML element in Inspector:
<img src="/assets/images/25388715424_65480dbf18_k.jpg&ZeroWidthSpace;&ZeroWidthSpace;&ZeroWidthSpace;&ZeroWidthSpace;&zwnj;&#xFEFF;&zwj;&#xFEFF;&ZeroWidthSpace;&zwj;&ZeroWidthSpace;&zwj;&zwnj;&zwj;&zwnj;&ZeroWidthSpace;&zwnj;&zwj;&zwnj;&zwnj;&zwnj;&zwj;&ZeroWidthSpace;&#xFEFF;&zwnj;&zwj;&ZeroWidthSpace;&zwnj;&zwnj;&#xFEFF;&ZeroWidthSpace;&ZeroWidthSpace;&ZeroWidthSpace;&zwj;&ZeroWidthSpace;&zwj;&ZeroWidthSpace;&#xFEFF;&zwj;&zwj;&ZeroWidthSpace;&zwj;&ZeroWidthSpace;&zwj;&zwnj;&zwj;&zwj;&ZeroWidthSpace;&zwnj;&zwj;&zwnj;&zwnj;&zwnj;&#xFEFF;&ZeroWidthSpace;&zwj;&zwnj;&zwj;&#xFEFF;&#xFEFF;&ZeroWidthSpace;&zwj;&ZeroWidthSpace;&zwj;&zwnj;&#xFEFF;&#xFEFF;&zwnj;" role="presentation">

From the terminal running Decap server:

error: Error handling {"branch":"master","action":"getMediaFile","params":{"branch":"master","path":"assets/images/25388715424_65480dbf18_k.jpg​​​​‌‍​‍​‍‌‍‌​‌‍‌‌‌‍​‌‍​‌‌​​​‍​‍​‍‍​‍​‍‌‍‍​‌‍‌‌‌​‍‌‍​‍​‍‌‌"}}: ENOENT: no suc
h file or directory, open '[snip]\assets\images\25388715424_65480dbf18_k.jpg​​​​‌‍​‍​‍‌‍‌​‌‍‌‌‌‍​‌‍​‌‌​​​‍​‍​‍‍​‍​‍‌‍‍​‌‍‌‌‌​‍‌‍​‍​‍‌‌'

Strange that the error reporting doesn't show the ZeroWidthSpace, but I guess its sanitizing its output like browsers do?

To Reproduce

1. Create a new post
2. Add a image
3. Look at preview window
4. Inspect the image, see console error.

Expected behavior
The image appears in the preview window and no errors present in console or terminal

Additional context
I had lots of trouble following the config guide, but eventually got image library paths and fields working correctly.
Tested frontmatter fields being quoted, unquoted, changed paths, all resulted in the same issue.
