Tooltips timing changed in 3.5.9?

Tooltips in webclient in 3.5.9 seem to popup much faster than before - the tooltip shows almost without any delay and actually gets in the way somewhat. Has the timing been changed in 3.5.9 and is there any way I can control it?

On a connected topic the tooltip behaviour change seems to affect use of solutions on iPhone also - in 3.5.9 if I tap on a button I get the tooltip and the button only actions the attached method on the second tap - I’m not sure if this is connected with the first question but I get the feeling it is!
