Autocomplete Removing Characters

[t-springborn]

On some occasions a sort of Autocomplete removes or changes characters.
The following instances have been observed:

Test Step	Expected Result	Observed Behavior
Add Capital letter after a special character, such as # or [	The letter is inserted and the character remains	The letter is inserted and the special character is replaced by a blank space
Add a line break	A line break is inserted and nothing else happens	A line break is inserted and the preceding character is removed
Add a line break in a list	A line break is inserted and nothing else happens	A line break is inserted and formatting is autocompleted to continue the list (i.e. indentation and * or numbering)

These were observed on an Android in Google Chrome using Gboard. Gboard autocomplete and autocorrect are turned off.
The behavior could not be reproduces in different contexts, such as Google Keep, or this issue editor.

Thank you for this detailed and helpful report. I will have to think on how to reproduce this issue as I don't have any Android devices.
