Content fetch was started for javascript 'https://fbstatic-a.akamaihd.net/rsrc.php/v2/yx/r/B67rGiOqstH.js' the completion of which happens long after the html docuemnt that started the fetch has gone (and the javascript context it references)

The delay is caused by the css fetches in front of it in the fetch queue timing out.

I believe I have fixed this, can you try the 2623 CI build and see if it reproduces again?

I have installed 2623 and will add a further note if there's a recurrence.

after a lot of testing it would seem the underlying cause of this and its related bugs has been found and fixed. If you get a new occurrence of something similar please file a new bug.
