First formatting works; second fails

Checklist prior to opening an issue

• I have followed fully the installation steps laid out in the documentation site.
• I have restarted jupyterlab.
• I have read the FAQ section in the documentation site.

Describe the bug
Given the following python code in a jupyter cell, it formats it correctly the first time, but fails the second time:

print("Foo: %s" % (len(df.loc[(df["Cloudfront-Is-Android-Viewer"] == "true") & (df["OS_TYPE"] != "ANDROID_OS_TYPE")])))

Formats to

print(
    "Foo: %s"
    % (
        len(
            df.loc[
                (df["Cloudfront-Is-Android-Viewer"] == "true")
                & (df["OS_TYPE"] != "ANDROID_OS_TYPE")
            ]
        )
    )
)

But if I click the button again, I get:

Jupyterlab Code Formatter Error
Cannot parse: 4:8: len(

Sorry for the late reply, I haven't given this project much love, I just kinda lost steam over the years as I got increasingly burnt out, but lately I have gotten a second wind (perhaps only for a brief period...)

FWIW I am in middle to a big refactor for the project (mostly due to the evolution of jupyterlab's plugin tooling), I can look into this bug after that.

Without the the refactor, the development envrionment for this plugin is just nightmare-ish to use, so that is currently trumping all tasks.

That's cool... I've been there on my own projects :-)
