Bug report

Bug summary

The example code to demonstrate how to rotate text is broken as of version 3.2.0. Either a bug has been introduced into matplotlib or the API has changed and the demo code is obsolete.

Code for reproduction

Please compare the result of the following two identical pages of code:

https://matplotlib.org/3.1.3/gallery/text_labels_and_annotations/text_rotation_relative_to_line.html

https://matplotlib.org/3.2.0/gallery/text_labels_and_annotations/text_rotation_relative_to_line.html

The pages are identical, but the code has different results.

Actual outcome

The improperly rotated text, in the second link above and in the latest version matplotlib v3.2.1

Expected outcome

The matplotlib v3.1.3 link above shows the expected, correct output.
