Created attachment 7037 patch

I applied another patch on top of that (restoring previous height calculations) to resolve this issue. https://git.xfce.org/xfce/exo/commit/?id=928a41aedd1b64fea3c1adb7991ccb6c2c9f5870 https://git.xfce.org/xfce/exo/commit/?id=7d62c589847200bddda2daa82bf300e34521775d
Maybe this change causes Bug 14737.
