The fourth call to `multi-line` doesn't seem to do anything

[duianto]

This package was just added as a transient state: SPC x n in Spacemacs. [editing] add binding for multi-line #14386

From some quick testing. Nothing seems to happen the fourth time multi-line is called.

The fifth time, it works the same as the second time, which starts the cycle over. but when it reaches a single line, then the next call to multi-line doesn't do anything again.

Expected

Calling multi-line should cycle to the next state with every call.

Observed

In a python file (.py). With the cursor inside the square brackets.

a = [1, 2, 3]

M-x multi-line results in:

a = [
    1, 2, 3,
]

M-x multi-line again, results in:

a = [
    1,
    2,
    3,
]

M-x multi-line a third time, returns it to a single line:

a = [1, 2, 3]

M-x multi-line a fourth time, doesn't change anything.

a = [1, 2, 3]

M-x multi-line a fifth time, starts the cycle again:

a = [
    1, 2, 3,
]
