SwiftUI modifier inside conditional compilation block indents incorrectly

[pdil]

When running swift-format I'm encountering the following issue where the SwiftUI modifier (.textInputAutocapitalization, located inside the #if !os(macOS) block) is un-indented instead of being left alone.

Linting on the same code returns warning: [Indentation] unindent by 4 spaces.

Here is my .swift-format file:

{
    "version": 1,
    "indentation": {
        "spaces": 4
    },
    "indentConditionalCompilationBlocks": false,
    "lineBreakBetweenDeclarationAttributes": false,
    "lineLength": 200,
    "multiElementCollectionTrailingCommas": false,
    "respectsExistingLineBreaks": true,
    "rules": {
        "NoAccessLevelOnExtensionDeclaration": false,
        "UseWhereClausesInForLoops": true
    }
}

The command I am running is swift format -irp . with Xcode 16 (16A242).
