Ultimaker 3 printhead crashes into very tall prints when finalising

[glx 29]

I just noticed recently that there is an issue when printing objects that reach closely to the maximum z-height of my UM3. The thing I printed is 198mm tall.
While printing everything is fine, the problem occurs when the print is finalised. The printhead moves slightly to the side, then the printer homes the z-axis that causes the build plate to raise a bit before lowering it. Since there is no extra margin the printed object crashes into the printhead. I had this happening three times recently (I don’t print that tall things often and I think it was the first time I printed something that reaches the z-limit). I honestly didn’t know what’s going on until I accidentally stood next to the printer yesterday when it happened. The times before I just heard a noise from a distance, yesterday I was like "wtf, that was that noise??". 
 

Apparently there are some more people with the problem (I asked in a Facebook-group to figure out if I probably did something wrong). 

 

The first time was a quite sturdy thing that I think even managed to damage the bed levelling sensor (at least since that time the active levelling fails at a 50% rate with triggering sometimes before the bed moves, before it was very reliable). 
 

I just "staged" a video with the thing and hitting the "lower build plate" option on the printer. 
 

I’m using the latest firmware, Cura 4.8 and the stock glass build plate.

Is there a simple fix (besides not printing such large things) that I can perform maybe in the end-g-code by myself or can this probably be fixed in some later firmware?

Maybe someone can check if that can also happen with other Ultimaker printers so it probably can be fixed :).

I would love an update on this from Ultimaker Team ! Same thing happened to me with a 100 mm tall print
