This is the same as <table><tr><td><textarea></textarea></td></tr></table>
where the Ua shrink wraps the table but the textarea inherit the parents width. This would cause a 0 width table, but currentl user agents rely on other attributes to get the intrinsic dimensions, like rows and cols for the table. In the SVG case, the UA could use default dimensions, like 300 per 300
