Description

Suppose an element stores a last remembered size with width/inline-size of 100px and height/block-size of 200px.
Then we add content-visibility: hidden so that the element uses that last remembered size.
Then we set writing-mode: vertical-lr.

What's the size of the element?

  • width/block-size of 100px and height/inline-size of 200px (i.e. we stored width and height).
  • height/inline-size of 100px and width/block-size of 200px. (i.e. we stored inline-size and block-size).
