No animation in example for "Animation attribute :text"

[gabor-braun]

Brief outline of the bug

In the documentation go to "Animation attribute :text". The snapshots in the first example look the same, no visible changes, even though this ought to be a working animation. (The second example showing no changes matches the text.)

Minimal working example (MWE)

This is an extended example from the documentation to include a multiple part node, too.

\documentclass[tikz]{standalone}
\usepackage{trace}
\usetikzlibrary{animations, shapes.multipart}

\begin{document}
\begin{tikzpicture}[my anim/.style={ animate = {
      myself:text = {0s = "red", 2s = "blue", begin on = click}}},
  text = white, fill = orange ]
  \traceon
    \node [fill, my anim] at (0,0) {A};
    \node [fill, rectangle split, rectangle split parts=2, my anim]
    at (1,0) {B \nodepart{two} C};
  \traceoff
\end{tikzpicture}
\end{document}

Here is the output with driver dvisvgm (with all optimization of the driver). Note that the text color is specified on text element, but animated on ancestor elements (with id pgf0t and pgf1t), so they have no effect. The letter C doesn't have even this animation.
