url returned by href parameter in LinkClicked is decoding when it should not (Markdown Widget)

[jspv]

Noted that authenticated links were breaking with signature failures, and tracing it down found that the link being returned is not the same as the link being clicked. example:

#!/usr/bin/python3

from textual.app import App, ComposeResult
from textual.widgets import Markdown

text = """
Here is an image of a dog created with DALL-E 3:

![Dog](https://some.site.us/tool?st=2024-12-22T18%3A07%3A22Z&se=2024-12-22T20%3A07%3A22Z)
"""

log_file = "linktest.txt"


class MyApp(App):
    def compose(self) -> ComposeResult:
        self.md = Markdown(markdown=text)
        yield self.md

    def on_markdown_link_clicked(self, message: Markdown.LinkClicked):
        with open(log_file, "w") as f:
            f.write(f"Original message={text}\n")
            f.write(f"Link received={message.href}\n")


if __name__ == "__main__":
    app = MyApp()
    app.run()

Output:

Original message=
Here is an image of a dog created with DALL-E 3:

![Dog](https://some.site.us/tool?st=2024-12-22T18%3A07%3A22Z&se=2024-12-22T20%3A07%3A22Z)

Link received=https://some.site.us/tool?st=2024-12-22T18:07:22Z&se=2024-12-22T20:07:22Z

Note the decoding. I would expect that the link received would be identical to the link in the Markdown.
