How can you NOT reproduce this?
Are you trying it on a 1-page document?
Try it on a 500-page book instead.
I just tried it with a 500 page book using
Okular 21.12.3 on Ubuntu 22.04 on a 1.6 GHz laptop.
I stopped counting when it hit two minutes.
The obvious approach is to render the current page
at the new size, then when you move to a new page,
render that, and so on.  Instead, okular acts as
if it is re-rendering the whole document in the new
size.

As for accidentally, the trick is to be using a
laptop where a slight flexing of the case causes
the machine to hallucinate mouse clicks and key presses.
It can also happen if you are *trying* to zoom in but
release the mouse button at the wrong time.

What I *really* want is the ability to replace the
menu of sizes with a list of sizes of my own choosing.
