Problem Description

The set font size for the plain text under "Settings/Appearance/Fonts/Plain text" is reset/not taken over in the IPython console completely randomly after the execution of a script or the restart of the IPython console, no matter what is set. It does not matter if the script contains syntax errors or not. The plain text size from the editor is not affected. It stays at the value that is set.

Question:
Does the set plain text size only apply to the editor or also to the IPython console because it adjusts both or is this a bug?

Would it be possible to add the text size setting for the IPython console separately in the settings?

What steps reproduce the problem?

1. Under Preferences/Appearance/Fonts/Plain text size --> set size to "11"
2. Create two small scripts and place them into the same directory:
3. script 1: "testclass.py"
4. code script 1:
   class test(object):
   pass
5. script 2: "debug.py"
6. code script 2:
   import testclass as testclass
   tc = testclass.test()
7. Run script "debug.py"
8. Close the IPython console where the script was running.
9. Now see that the text size in the newly created IPython Console has changed to it`s default value (e.g. 10), but in the settings the text size still stands on "11".
10. NOTE: When I remove the "tc =" from the script "debug.py" and run the code, the IPython Console text size remains on "11"... really strange.

What is the expected output? What do you see instead?

I expect that the text size in the newly created IPython console will not change depending on the code in the script.

Hey @Se3ri0us, thanks for reporting. I've also noticed this problem, but I don't know why it happens.

We'll try to fix it in our next version after 5.4.3 because I also think it's very annoying.
