Steps to reproduce

Guess this is the same with any kind of firepad integration with ace. Use the above link to test this behaviour.

Expected behavior

when i enter multiple lines of code, line by line and press ctrl+z(undo) . I expect the undo function to remove only the code that i am entering in current line. you can test this in expected behaviour in ace editor demo - http://securingsincity.github.io/react-ace/

Actual behavior

when i enter multiple lines of code, line by line and press ctrl+z(undo) , it removes all the code in the editor. use the link provided in testcase section above

@mbsyaswanth can you explain what you mean by "enter multiple lines of code"? Do you mean pasting multiple lines in at once or do you mean typing a few lines of code manually?

I'm sure he means typing in a few lines of code manually. I can reproduce this issue.
