Tabline extends past scope

[leslykinzel]

Summary

Tabline visually extends beyond its scope unless there is text after it. (This may affect any code that uses indentation to define scope)

Steps to trigger the problem:

1. Create a new python file.
2. Create an indented structure, such as a function or a loop.

For example:

def main():
    print('I love Zed')

3. Add some newlines after it.
4. Add some more text below the indented code, and see the tabline go back to its correct length.

For example:

def main():
    print('I love Zed')

if __name__ == '__main__':
    main()

Now the tabline extends out of scope of the if statement as long as there is a newline after it.

Actual Behavior:

You should see the tabline extending one extra line below the scope, as long as there is no text after it.

Adding any text on a subsequent line will fix this. This issue only occurs when an indented structure is the last piece of code in a file.

Expected Behavior:

The tabline should not extend beyond the scope unless there is another line ahead that is in the same scope.

These screenshots are from the same file in vscode:

This issue can be temporarily avoided by adding "ensure_final_newline_on_save": false to settings.json and ensuring that the file does not end with an empty line.
