Possible to set transparency on first part of colored prompt

[emilast]

Is it possible to have the first part of a colored prompt to be transparent?

This is what my prompt looks like in in Windows Terminal:

I have enabled "acrylic" to make the background semi-transparent and blurred and it would be great if the first minimal dark-grey part of the prompt to be transparent as well. Is it possible?

I've seen this go wrong a few times already, yet I have no idea why. It takes transparent but doesn't work. Maybe we should resort to writing ANSI all the time, but that a large refactor.

No problem! Thanks for this great project! 👏

I was looking at this one, The difference between the user prompt and the separator is that the user prompt is being written with a black background, however the circled separator here is written with a black foreground, I suppose in WT the background may be be to be rendered transparent, however the foreground doesn't seem to.
