FlipX not working in WebGL renderer

[mishelen]

This all happens on the same model. If you render it on canvas, then without problems, when on webgl renderer, the flipping does not go away. This example model is from pro version and taken from spine-runtimes repo and has version 3.6.39.

Im also try work with the same model maden in essential version of spine. Model has version 3.6.2 and switching between canvas and webgl cause the same problem.

I do everything on the branch spine-ts.
