PSA: Add dir=“auto” to your inputs and textareas

Worth noting that the spec on this states the following:

> The heuristic used by this state is very crude (it just looks at the first character with a strong directionality, in a manner analogous to the Paragraph Level determination in the bidirectional algorithm). Authors are urged to only use this value as a last resort when the direction of the text is truly unknown and no better server-side heuristic can be applied.

which seems to be their justification for not having this be the default behaviour.
