[Skeleton] Height of text variant does not match given font-size

Steps to reproduce

Steps:

1. Open this link to live example: https://mui.com/material-ui/react-skeleton/#inferring-dimensions

Current behavior

The height of the Skeleton is less than the given font-size. It appears to be transformed/scaled down.

Expected behavior

I expected the Skeleton's height to equal the given font-size. Ideally, the Skeleton would take up as much vertical space as the line-height, but display the gray rectangle at a height equivalent to the font-size.

Total vertical Height matches line-height, as expected. But the gray rectangle is 67.22px when the font-size is 96px. Why is it being shrunk down by 30%?
