Transient prompt arrow color change lags by one line

[ErGoVega]

When attempting to set the transient prompt arrow color to change from green to red when an error occurs, the first command always shows as green (the default color) even for commands that error, and the following commands always show the arrow color the previous command should have had.

I've tried searching for similar discussions but couldn't find anything similar.

Everything was run in MacOS Sonoma using iTerm2 for the terminal.

Any ideas on what could be the cause?

@ErGoVega Unfortunately, that's impossible because a transient prompt is rendered before the command is actually executed.

[JanDeDobbeleer]

Transient is always the prompt before the command is run. So that makes sense.
