Please make sure that you've checked the following before submitting your pull request. Thanks!

• Check that your code compiles by running npm run build
• Ensure that the PR targets the correct branch. Check the milestone or fix version of the ticket.
• If this is the first time you're submitting a PR or even if you just need a refresher, consider reviewing our style guide
• Do not bypass Angular sanitization (bypassSecurityTrustHtml, etc.), or justify why you need to do so
• If displaying markdown, use the markdown-wrapper component, which does extra sanitization
• Do not use cookies, although this may change in the future
• Run npm audit and ensure you are not introducing new vulnerabilities
• Do due diligence on new 3rd party libraries, checking for CVEs
• Don't allow user-uploaded images to be served from the Dockstore domain
• If this PR is for a user-facing feature, create and link a documentation ticket for this feature (usually in the same milestone as the linked issue). Style points if you create a documentation PR directly and link that instead.
• Check whether this PR disables tests. If it legitimately needs to disable a test, create a new ticket to re-enable it in a specific milestone.
