In Bitbucket version 8.10, a feature was released that provides previews for HEX color values (valid values such as #123). These can consist of 3, 4, 6, or 8 digits and may include letters from A to F. Since the "#" symbol is also used for pull request (PR) links, Bitbucket prioritizes PR IDs over rendering HEX colors. However, if there is no corresponding PR ID, it defaults to displaying the HEX color code. It would be preferable if the color code only appeared when enclosed in backticks(`#123`), as this would prevent conflicts with the pull request ID syntax.
