tex_to_color_map colors wrong substring when using subscript then superscript #4427
Description
Description of bug / unexpected behavior
In MathTex the option tex_to_color_map does not color the right substring when using subscript then superscript. See example in code (very short).
Expected behavior
If I use MathTex(r"x_i^k", tex_to_color_map={"x_i": RED}), I expect the x and the i to be RED, and the k to stay WHITE. However, instead the i is WHITE and the k is RED.
How to reproduce the issue
Code for reproducing the problem
from manim import *
class TestScene(Scene):
def construct(self):
text = MathTex(r"x_i^k", tex_to_color_map={"x_i": RED})
self.play(Write(text))
