Restore Accessibility for Dropdown (#16576)
* Restore #10096/#8638 and re-fix #15172 This PR restores the vendored and patched dropdow from #8638. It however, abandons the calls to `click()` using instead the default dropdown click calls instead. This prevents the issue of the dropdown grabbing focus permanently however, this may have negative effects on the effect of focus on the dropdowns. Of note, the behaviour of the template selector dropdown on the repo creation page is slightly odd - I don't believe that this odd behaviour is caused by this PR but rather by the feed source for this. I suspect that the dropdown should be adding a delete button to its selection. Fix #15172 References: #7057 Signed-off-by: Andrew Thornton <[email protected]> * leverage fomantic-build instead Signed-off-by: Andrew Thornton <[email protected]> * as per jookia Signed-off-by: Andrew Thornton <[email protected]>
