2019: Project Align then trim affects surfaces

[mcgeecardesign]

Just wanted to note a problem I'm noticing with 2019. Typically when you go to project-align a surface to another, and then go to trim that surface down to something smaller, it wouldn't change the actual aligned surface. In 2019 that's not the case. I'm often finding trims are screwing up my project-aligns. Hard to explain, so here are two photos as an example. I don't see any benefit to this, it's infuriating!

Before trimming, orange surface proj-align with history onAfter trim, surface now aligns to that new trimmed edge.

I have checked if the same problem happens in Surface 2017 but the surface remains the same even after trimming while keeping the history. 

In your case this might be a bug in a software. However, you can solve this issue by deleting the history first before trimming the surface.

Thank you

Which is what I do. But sometimes I forget because I'm not used to it yet.

Hi there, would you be willing to share your file?  I'm not seeing this behavior in Alias 2019.0 or 2019.1.

So unfortunately I've just left my job that had 2019 installed. I have 2018 at home. If I have 2019 at my new position I can certainly mock it up and send a sample.
