Instead of asserting the exact Markup value, we can make the test more robust by checking the actual content.

This is similar to the approach used in OCA/account-financial-tools#2305, where the test was updated to verify the relevant content rather than the exact HTML/Markup representation.

self.assertIn(
"Test Description",
self.lead.project_id.description,
)
