OC.addStyle is not a function

[gumaerc]

I recently got full text search up and running on my Nextcloud instance. It works well, except for the fact that I can't really read the search results well at all because it's black text on a dark gray background. It appears as if the code is attempting to apply a stylesheet, but using the deprecated OC.addStyle function to do so. This is the stack trace:

I'm running Nextcloud Hub 8 (29.0.3). I don't think any other info is necessary here. OC.addStyle should be replaced with OCP.Loader.loadStylesheet.
