Wrong behavior of styles with multi-instance modules
Choose an image, discard history stack, duplicate.
Open original image in darkroom, enable "Denoise (Profiled)" with params: Mode: Non-Local Means, Blend mode: Lightness.
Create new instance of same module "Denoise (Profiled)" with different params: Mode: Wavelets, Blend mode: Color.
Switch to lighttable, create a style from the current history stack, include only "denoise (profiled)".
Open duplicate image (with empty history stack), apply newly created style.
There will be 2 instances of "Denoise (Profiled)", but only second will be enabled, and none of them will have correct params saved.
This bug is probably related to bug #9300

This one is mostly fixed.
The only issue i have noticed: after applying style (created as explained in bug description) to history-less image, profile list for second instance of "Denoise (Profiled)" does not automatically repopulated - i.e. 1-st instance have correct profile list, but 2-nd instance have empty profile list.
It's get repopulated after you switch to lighttable and back to darktable.
