    This text should not be autosized (its computed font-size should remain 16px), as autosizing usually causes text to wrap onto more lines, which might cause it to overflow the block's max-height (the float:left doesn't affect this).<br>

            This text should be autosized to 40px computed font-size, since the parent is float:left so the height is considered to be unconstrained (ancestors of the parent are ignored).<br>
