Command line flag --code-style=android_studio has no effect in v0.49.0

[ghaiszaher]

Expected Behavior

ktlint --code-style=android_studio should behave exactly like the deprecated flag ktlint --android, this is also stated in the warning message printed after running ktlint --android:

Option '--android' / '-a' is deprecated and replaced with option '--code-style=android_studio'. Setting '.editorconfig' property > 'ktlint_code_style=android_studio' might be a better idea for a project that is always to formatted with this code style.

ktlint_code_style=android_studio in .editorconfig works properly, but --code-style=android_studio in command-line has no effect.

Observed Behavior

After running the command ktlint --code-style=android_studio --log-level=debug {filepath} on a file, the following output is observed:

[...]

Summary error count (descending) by rule:

However, running ktlint --android --log-level=debug {filepath} will show:

[...]

[main] DEBUG com.pinterest.ktlint.cli.internal.KtlintCommandLine - Exit ktlint with exit code: 0

Note that ktlint_code_style: android is not mentioned in first command and the reported errors are different.

Steps to Reproduce

1. Create a new file MyEnum.kt with following content:

enum class MyEnum {
    SomeEnumValue
}

2. Run ktlint --android -> no issues reported
