I save someone a million dollars a year knowing how to properly index and query DynamoDB, not about what <doctype HTML> means or whatever.
If someone said that to me in an interview my next question would be "Why did you apply for a senior frontend dev role then?"
Nobody cares about text-size-adjust and other such nonsense.
Senuor frontend devs do care about that, because it affects the display quality, accessibility, and readability of a web app on a mobile device. If you get text size wrong on a site like Amazon or Twitter you could push tens of thousands of people to stop engaging with the site. Imagine if the "Buy Now" text on a button overflowed because the font was too big so it read "Buy no" instead. That would have an impact on revenue.
