Description:
Sometimes when pressing Enter/Return to create a new line, auto-correct kicks in and changes the capitalization of the word, according to the defined set of rules. 

So if I start a new line, type "intentionally-lowercase" and press Enter, it gets corrected to "Intentionally-Lowercase".

When I then press ctrl+z, the word gets reverted to original spelling, but the newly entered newline is deleted. So if I then go to the end of the line and press Enter again... the autocorrect is applied again and the first letter is changed to a capital letter. So the user is stuck in a frustrating loop.

Note that the behavior for entering a newline is different from the behavior when pressing the spacebar.

If I start a line with "intentionally-lowercase" and then press Space, it adds a space and applies autocorrect. I can then press ctrl+z and it only undoes the autocorrect, keeping the space that I've entered, so I can move on with editing the document.

There's an unintuitive difference in behavior then: when pressing Space, autocorrect is treated as a separate step that can be undone. When pressing Enter, the newline and autocorrect are treated as one and can only be undone as a whole, leading to confusion.

I personally thing the behavior that's applied when pressing Space is more intuitive and it would be great if the same behavior was applied when pressing Enter

Steps to Reproduce:
1. In a new line, write a word starting with a lowercase letter
2. Press Enter
3. The word is now capitalized
4. Press ctrl+z

Actual Results:
The word is no longer capitalized, but the newline is gone

Expected Results:
The word is no longer capitalized, but the newline is still there and the cursor doesn't change position


Reproducible: Always
