@ShaneK Hi! I've mentioned you since you addressed #30684.

I couldn't comment on the other issue, that's why I opened this one.

Fun thing about your reproductions, they actually had two different issues to solve (described in the PR)! Either way, my PR should address both of them.

Current dev build, if you'd like to try:

8.7.12-dev.11764961567.138743ff

@ShaneK Love to hear that! I guess I'm hitting ionic hard enough to break it!

I've tried 8.7.12-dev.11764961567.138743ff build on my project and it's solved partially.
On initial load works perfectly, but if I navigate to the child route afterwards, the backdrop will stop being interactive

Sorry, can you provide more information on how to reproduce this? I seem unable to

@ShaneK Okay, the issue is fixed with ion-router-outlet, but still happens when using angular's router-outlet. I was using it in my project to enable the viewTransitionsApi between child route transitions.

Here i'll drop the updated stackblitz with the reproduction

Hey @kumibrr ! Could you try my latest dev build? I accidentally left out the refreshing state that's often required for Angular because of how it uses data bindings.

New build:

8.7.12-dev.11765060985.14ad27fb

[kumibrr]

@ShaneK It's working flawlessly with the latest build! 🎉
Thank you so much for your work! 🚀
