phpcs complaining about indentation of javascript files
Since 2018.3 the following is happening on all js files:

I've tried changing phpcs and even disabling it all together, but it keeps saying this about every js file.
Other computers/users have this issue as well. For now the only solution has been to stick to 2018.2. Also the 2018.3.2 update does not fix it.
Could this be a (new) configuration issue in the new version? If so how can I fix this? Or is it a bug?
Thanks!
edit: Could it be related to this issue:

That it isn't picking up the phpcs.xml anymore, because it has a value of:
<arg name="extensions" value="php"/>

Yes but disabling doesn't really fix the issue.
I found that in 2018.3 it ignores the extensions setting in phpcs.xml for some reason, while it doesn't in 2018.2.
I can fix it with an exclude-pattern for .js files, but again that is just avoiding the issue.
Why does the extensions setting not get picked up anymore in 2018.3?
Because of a bug, please check the link Dmitry pasted in his reply: https://youtrack.jetbrains.com/issue/WI-44308
