Writing-mode should not be inherited from CSS

The 2D context is not supposed to inherit the writing mode of the
parent \<canvas> element.

According to the spec, the algorithm that specifies the canvas text
rendering properties is defined here in the spec:
https://html.spec.whatwg.org/multipage/canvas.html#text-preparation-algorithm
In particular, step 5 of the algorithm.

This test verifies that the vertical writing mode has no effect on
\<canvas> element.
