Remix appending comma to end of HTML bodies when loader is present

[cill-i-am]

Bit of a strange one here. So we have had this comma appended to the end of our <body/> and I think it is caused by Remix. It occurs on all pages, unless a page does not have a dedicated loader and has a clientLoader - for some reason none of the below code occurs then. I am really at a loss as to how to fix this, so any help would be very appreciated

The injected code looks like this:

<script>window.__remixContext.streamController.enqueue("AN_ARRAY_WITH_A_LOAD_OF_LOADER_DATA");</script>
<!--$-->
<script>window.__remixContext.streamController.close();</script>
<!--/$-->
<!--/$-->
","
<script>function $RC(a,b){a=document.getElementById(a);b=document.getElementById(b);b.parentNode.removeChild(b);if(a){a=a.previousSibling;var f=a.parentNode,c=a.nextSibling,e=0;do{if(c&&8===c.nodeType){var d=c.data;if("/$"===d)if(0===e)break;else e--;else"$"!==d&&"$?"!==d&&"$!"!==d||e++}d=c.nextSibling;f.removeChild(c);c=d}while(c);for(;b.firstChild;)f.insertBefore(b.firstChild,c);a.data="$";a._reactRetry&&a._reactRetry()}};$RC("B:0","S:0")</script>
<script>$RC("B:1","S:1")</script>

And here is an example of it:

Even removing the outlet etc from the route results in the same:

Here's a pared back example of what I mean. The only loader that is run on the /test route is the root loader. Notice how adding a client action removes the comma? Otherwise it remains no matter what I do

I had the same problem in my project and I found an extra comma in the entry.server.tsx
