This document demonstartes the mozilla content size bug.<br>=0A=

the expected results are contentWidth =3D 150 and contentHeight =3D =

Note that the bug only occurs with the width<br>=0A=
In case you did not notice. getContenWidth in Mozilla will actually =

If the child layer's area does not extend beyond the parent layer's area =
