I have recently discovered that the kmail message panel has a zoom feature, <ctrl> <scroll_mouse_wheel>.  It is good, but it changes suddenly.  Whenever I select a different message to look at the zoom returns to standard size, that is good.  

There are a couple of ways that the zoom factor could be remembered; such as keeping the zoom factor unchanged across all messages until it is changed again (or kmail is restarted), doing the same thing on a per message basis, or continually reverting to 1:1 size.  

The problem is that it falls between these behaviours.  When I adjust the zoom it is remembered, but not used when a different message is looked at.  Adjusting the zoom on a new message adjusts it from where it used to be, not from where it is.  I find this visually odd.  


Reproducible: Always

Steps to Reproduce:
Zoom in on a message, view the next message and come back to the original message.  It is displayed at 1:1 size.  Touching the <ctrl><scroll_wheel> makes the zoom jump suddenly to close to (but not the same as) what it used to be.  

It is a mater of opinion about what the "correct" behavior is in this situation, but I find the current behavior odd.  

Actual Results:  
Zoom jump suddenly.

Expected Results:  
Zoom should be smooth.  (Preferably from the old value.)
