<\/script> tags in post content would sometimes be recognized as actually ending the script tag, even when escaped (not exactly sure why). This is fixed by encoding the < > characters in unicode.

As suggested by @ryantology here, the
@jsondirective should by default use encoding options that are safe to use in HTML output.We encountered a similar problem recently in Flarum that we fixed in a similar, albeit incomplete way. Once we upgrade to Laravel 5.5, we can then use the
@jsondirective.Technically, this is slightly breaking backwards-compatible, but doing so for the XSS-safety of the people, so I hope this is okay.
This also adds test and slightly prettifies the compiled output. :)
