In the MR overview page is just a `<div>` with an onclick handler

making it not picked up by screen readers, vimium and other accessibility tools. Please add `role=button`, a tabindex, space/enter handler, focus state, and selection state. Or just use a `<button>` for interactive elements, or a `<details>` Element.
Please also consider adding a11y-related checks (eslint/a11y, or static analysis tools etc) in your deploy process so these kinds of a11y errors are prevented from happening in the first place.
