Hi @bluesmoon , @ceckoslab , @andreas-marschke , @ashenoy2014 , @nicjansma
could this PR be Merged ?

@liufei @SaschaBrechmannVHV Thank you for the changes. We will take a look soon. In the mean time, have you thought about what sort of test can be added to cover this? If you can, that would be super helpful!

[nicjansma]

Thanks for opening this PR @liufei. I've added a test (in our internal repo), and will backport it here shortly. Since I can't push to your remote, I'll commit to our main branch and close this PR out once it's available.

@ashenoy2014 @nicjansma You're welcome. Due to the incompatibility of the MacBook Pro M1 chip with e2e testing, there is currently no solution available, and therefore the test has not been submitted.

@SaschaBrechmannVHV Although the PR won't be merged, I appreciate your attention to this issue and hope that all Lottie users won't be affected by this problem and can still use Boomerang normally.
