Bug

Markers do not render on both iOS and Android with latest v12.1.0

Steps To Reproduce

Issues without reproduction steps or code are likely to stall.

1. git clone https://github.com/ghanemabdo/react-native-svg_marker_sscce
2. cd react-native-svg_marker_sscce
3. yarn
4. react-native run-ios
5. sample code renders on simulator/device without markers

Describe what you expected to happen:

1. The Path rendered from the sample code should show a marker at the end of the path. The marker does not appear

2. Using snack on the web with the same sample code, markers show correctly
