Wordpress 5.0 issue

[Sitetools]

When upgrading WordPress to 5.0 Autocomplete is breaking, below is what I'm using.
There are no suggested pages displaying as I add chars to the form field.
I can't see any JavaScript or xhr errors in the console.

'link' => new Fieldmanager_Autocomplete(
'Button link, start typing page title',
array('datasource' => new Fieldmanager_Datasource_Post())
),

@Sitetools Could you test whether this is the same issue as #710 and is therefore fixed by #717?

I installed #717 and this didn't fix it all the select2 controls as not loading

Fixed via #757
