Fix page title not rendering correctly, causing flaky tests

[elceebee]

Context

We've had a few flaky tests where the page title is being checked. They are flaky when the Faker data provides a name that has an apostrophe or other character in it.

Changes proposed in this pull request

Add html_safe to browser title so the characters will be renedered.
