P: Gradients with alpha transparency behaving inconsistently

I'm not sure why this is becoming a problem now, but on Photoshop version 20.0.3 and 20.0.2, gradient overlays that use transparency, whether by a gradient fill layer or as a layer style, behave inconsistently when Legacy Compositing is off.

Certain actions, like editing text, will cause the opacity of gradients in the document to change. If the gradient is a layer style on a layer, trying to edit that blending mode will cause the gradient opacity to change again.

This is bug is a real hassle to work with when my gradients are seemingly changing for no reason when doing other things in a document.

Here is an example file that demonstrates this issue. Try editing the type. Then try double-clicking on the Gradient Overlay effect.
