ExtendedScript - Changing the Mogrt title makes it blank

[Simple31480666me6h]

I am trying to change the text content of a Mogrt file using ExtendedScript but whenever I execute the code below the text becomes blank, and the Mogrt name on the video track resets to "Graphic". It's like everything's been reset to default.

var sequence = app.project.activeSequence;
var videoTrack = sequence.videoTracks[0];
var mogrt = videoTrack.clips[0];

mogrt.components[3].properties[0].setValue('test', 1)

The Mogrt I'm using is the Basic Title one found in the Essential Graphics tab, alternatively I used the type tool as well and the same happens in both cases.

Running on Photoshop 23.4.0.

The API is designed to work with .mogrts authored in After Effects, like 'from_ae.mogrt' (included in the PProPanel sample).
