Release description markdown not displayed correctly

When i create realease, decription contains some markdown including tables. When i go to Project overview -> Releases i can see that Description is not displayed correctly, tables has no borders and no spacing, headings has no underlines and so on. When i edit this release description and click preview, markdown is displayed properly. Why it is not so in Releases page?

Reproduction

View this latest release on https://gitlab.com/rayana/minimal-ruby-app/-/releases

Proposal

We need to ensure that the Release description is being rendered as GitLab Flavored Markdown. We have a jQuery method called $.fn.renderGFM() which may not be getting executed on the Release description. If we find that renderGFM is being called on the Release description, then we may be inadvertently removing the styles somewhere, and will need to fix the regression.
