Bug summary

matplotlib.use('tkagg') and matplotlib.use('TkAgg') do not do the same thing, the former freezes until show or pause is called, the latter is interactive

Additional information

I have tested this on Windows 10 and 11 using PyCharm (223.8617.48 and also the most recent 232.10319.12). I have tested with matplotlib 3.9.0 as well as a few older versions. I have tested in multiple Python versions, including 3.11.9 and 3.9.13. It seems to work with matplotlib 3.8.3.
