End of Line problem in Adobe apps

Glyphs
1

I’m creating contextual end swashes.

sub @SwashEndBases' by @SwashEnd;

But when I add an Ignore Sub rule before to only have the replacement at the end of a line …

ignore sub @SwashEndBases' @All;

… the replacement stops working in Adobe apps (but not TextEdit for example).
The All class is created by Glyphs. When I limit the class to the automatic “AllLetters” it starts working again.
So it feels like something in the All class is always matching the way Adobe treats line endings or it is breaking the feature somehow.
Anyone knows what is going on?

Here is the All class in case it matters.

What happens if you enable the world ready composer in indesign? (This is not a proper solution but a debugging step)

Same result for both.

I could narrow it down to the space character. If I remove spaces from the All class, it starts working again. But I don’t want replacements at the end of the words that aren’t at the end of the line. For now, I added another Ignore rule to fix this.

    ignore sub @SwashEndBases' @Spaces @All;

Doesn’t feel like an ideal solution, but it works.

It’s worth mentioning that this seems to be a new behaviour in Adobe apps. I used the same code with a font created in 2019 and it definitely worked back then, but this font is now also not showing automatic end swashes anymore in InDesign.
