Questions on a published form were set at 12px in the style used elsewhere for small captions above a box, like "Form title" on a settings screen. That is too small for a sentence somebody has to read and answer, and it left the question as the smallest text on the page — smaller than its own help text, smaller than the answer being typed into it, and smaller than the introduction above it.
Questions are now set at normal reading size, matching what the form builder has been showing in its preview all along.
Three fixes for people using a screen reader came with it. Help text under a question is now properly attached to the box it describes, so it is read out instead of skipped. Multiple choice and checkbox questions now announce their question correctly — the link between the two was pointing at nothing. And a required multiple choice question now shows its asterisk, which had been invisible.
