Text will be horizontal centered if there is no heading - Is this the correct behaviour?

I am using the following code

struct MarkdownView: View {
    @ObservedObject var viewModel: MarkdownViewModel

    var body: some View {
        Markdown {
            viewModel.markdownString
        }
        .textSelection(.enabled)
        .markdownTheme(.gitHub)
    }
}

and

    private func setupMarkdown() {
        // Define your markdown content
        viewModel.markdownString =
"""
hello world

bye
"""
        // Create the SwiftUI view and pass the markdown content
        self.markdownView = MarkdownView(viewModel: self.viewModel)
        
        // Embed the SwiftUI view in a UIHostingController
        let hostingController = UIHostingController(rootView: markdownView)

        hostingController.sizingOptions = .intrinsicContentSize
        hostingController.safeAreaRegions = []
        
        // Add the hostingController as a child
        addChild(hostingController)

        stackView.addArrangedSubview(hostingController.view)
        
        hostingController.didMove(toParent: self)
    }

The outcome is

However, by adding header into the content

        viewModel.markdownString =
"""
hello world

bye

# Heading
"""

The text will properly align to left.

I was wondering, is this an expected behavior? How I can ensure the text is always left align? Thanks.

Sorry. I just notice that I can place .frame(maxWidth: .infinity, alignment: .leading) to make it work.

struct MarkdownView: View {
    @ObservedObject var viewModel: MarkdownViewModel

    var body: some View {
        Markdown {
            viewModel.markdownString
        }
        .frame(maxWidth: .infinity, alignment: .leading)
        .textSelection(.enabled)
        .markdownTheme(.gitHub)
    }
}
