fix(material/tabs): glitchy animation in rtl with lazy-loaded content (#31535)

When the tabs have lazy-loaded content, their height can be zero to begin with. This appeared to hit a Chrome bug where animating the `transform` on a zero-height element in RTL was interrupting the animation.

These changes fix the bug by setting a minimum height.

Fixes #31503.
