Zooming into large PDF file results in crash

Report mentioned zooming into PDF consumes all the memory and going to last pages would make it worse.

Using 6.5.3 version of example pdfviewer with Qt 6.5.3, opening and zooming into a large PDF file for example 50 pages long, can consume all the memory.

Using the same or newer pdfviewer example with 6.5.8 or 6.8.2, going from >4000% zoom and 3GB memory usage -> >6000% crashes the app.
