I tried to replicate your issue and while the dev tools show it as alt the source code shows alt="", so WordPress is not stripping the quotes, it’s just the dev tools being concise. But even if it was, they’re equivalent so alt and alt="" are the same.
As for why the dev tools display alt, it’s because the dev tools don’t display the HTML, they display the DOM
