It's not a requirement in theory, but how text aligns with the elements around it is massively important for usability. When you flip text, without flipping the layout and surrounding elements, it almost always becomes less useable as the text was originally designed with certain alignments in mind that no longer occur. Also, speaking as a frontend engineer, it's usually much easier to flip everything as not doing so also increases the chance of weird text alignment/wrapping & overlap bugs.
