It was OK before 0.9.59
If you are using quartz-wm then no, it wasn't OK. The breakage was less visible because of the position caching, but it was still broken in many cases, and it was broken with correct wms too.
Now it should work better with wms that implement the spec, which unfortunately means it's worse with broken wms. I think that's a reasonable trade-off.
