Dose not work on to big pages

[nanderer]

Hi,

if you try to save big pages loading lots of pictures using javascript it works fine when you save only the first pictures but when you scroll all the way down and then use singlefilez it runs trough all 3 steps but then a long time nothing is happening anymore and at the end you get some obscure error message.
Steps to reproduce:

1. go to https://mangareader.to/read/bleach-color-edition-55958/en/volume-1
2. chose vertical scrolling
3. scroll slow enough all the way down so all images are being loaded
4. initiate singlefileZ
5. wait until it crashes

i tried it in firefox and chromium, all the same result, as it crashed on my intel i5-8365U thinkpad with 8GB of ram i tried it on my big ryzon machine with 16GB of ram, it wasnt maxed out but it still failed

error on linux with chromium 8GB of ram machine:

error windows firefox 16GB of ram machine:

thanks for looking into this and hopefully fixing it in advance
