Hi, I was testing the new alpha 4 of Godot with my project, but I noticed that the rotation that is displayed in the tiles is not the same as in the 3.0.6 (it shows flipped), but when I try in the alpha 3 it conserves the same rotation.


Steps to reproduce:
-Create a project in the 3.0.6 stable release that uses Tilemap with rotated Tiles, the ones that I saw have problems are with -90 and 90 degrees.
-Open Godot 3.1 alpha 4, when it loads the Scene you will see that the tiles have not the correct orientation.
-Also when I rotate a Tile in the tilemap editor, shows a weird image after the rotation.
Also I see that only occurs when using GLES 2.
