Syntax highlighting in python gets weird when line begins with `*`

[TansyArron]

I initially reported this in the wrong place. See microsoft/vscode#91456 (comment) for the initial report.

Expected behaviour

Syntax highlighting of arguments should look like that below when the line begins with any argument, including *.

Actual behaviour

When a list of arguments is on more than one line and a * is the first argument on the line, the syntax highlighting gets very odd. Everything on that line is a pale green color.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

Everything is fine here:

def my_func(*, foo, bar, baz=True)

Here the middle line turns pale green:

def my_func(
  *, foo, bar, baz=True,
)

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)

@TansyArron, thanks for letting us know about this. We haven't been able to reproduce this problem. What theme are you using? Do you have any other extensions installed? Thanks!

[TansyArron]

All my installed extensions (is there a way to get this as a text list?)

Theme is "monokai"

Thanks for looking into it, it's a pretty minor weird thing :)

@TansyArron, I still haven't been able to reproduce the problem. I expect that it is caused by one of the other extensions you have installed. Try disabling them all and then re-enable one-by-one.
