With the exception of text introduced using the before/after selector 
[1], and focusable content that is reordered using things like FlexBox 
[2], CSS does not tend to affect screen readers.

The use of deprecated HTML tags might be a different story. I think it 
would depend on whether emulation mode changed the way the accessibility 
tree was constructed, as well as how the content was rendered. Do you 
have an example you can point to?

None that I know of, or could find based on a few minutes searching.
