We typically rely on the placeholder for accessible labels in a lot of places, e.g.:
For further reading, see placeholders are not accessible. Tl;dr - placeholders aren't accessible to screen readers and are only useful before the user has entered text
Note
We likely want this to enforce this for all <Input /> elements. There's not a clear solution here yet (as there's so many ways to label an element). The simplest solution is to always enforce that we have some label on these elements, issue here for that: https://github.com/sourcegraph/sourcegraph/issues/36645
