messages where markdown formatting overlaps slack formatting are rendered incorrectly

[twouters]

source bot message:

text: 'message with _in and url <https://example.com/contains_too|example_url>'

rendered body on matrix side:

"formatted_body": "message with <em>in and url &lt;<a href=\"https://example.com/contains\">https://example.com/contains</a></em>too|example_url&gt;

Edited initial comment because there should not be a space after the underscore in the test.

it("Should handle named links mixed with underscores", () => {
	expect(markdown.toHTML("Hello _sup <https://example.org/has_too|example>"))
		.toBe("Hello _sup <a href=\"https://example.org/has_too\">example</a>");
});
