The canvas specification maintains: These shapes are painted without affecting the current path, and are subject to shadow effects, global alpha, the clipping region, and global composition operators. [0]
But no browsers I tested actually implement the "clipping region" part. Should this be removed for backwards compatibility reasons? Should we introduce a new method of clipping text be introduced, or should we just require users who want to draw clipped text to draw to a scratch canvas and use drawImage to copy the pixels?
