SWFs with mangled tag order play fine in original Flash Player but bug out horribly in Ruffle #9533

Describe the bug

Some Flash clones like Vectorian Giotto sometimes put DefineMorphShape tags before the referenced DefineShape tag. This causes no issues in the official Flash player but causes objects flicker in and out of existance in Ruffle.

Expected behavior

In the example movie, the stickman moves across the screen rocking backwards and forth in a rudimentary walk cycle.
