potential performance regression in latest release

[joprice]

I've been using svgs from the flag-icons library https://github.com/lipis/flag-icons/blob/main/flags/4x3/es.svg and loading them via the react-native-svg-transformer/react-native transform. After updating to 15.15.0, I'm seeing 8-10 second freezes on the ui thread. This doesn't happen with simpler svgs. The above svg is 10x the size of the others and has many quite intricate designs, and could be simplified, so I'll probably swap it for something less high resolution, but I wasn't having this issue with the previous versions of the lib.

Thank you for bringing this issue up, I'll try to investigate it further.
