Performance on object with 4550 words starting to feel chunky and slow

I run a TTRPG campaign out of Capacities using an object as my "DM Guide". The objects are broken down by book and chapter "B1-C2" for example representing Book 1: Chapter 2. Currently, I am operating out of a chapter object that is 4550 words long and already showing signs of degrading performance. Especially noticeable when dragging blocks to relocate them it becomes virtually unusable where I now just cut/paste instead of dragging. I can also sense a feeling of lagging text entry at this point in the object. I use quite a bit of formatting tricks to make things visually clear and organized but nothing extreme. I fear exporting this object as markdown and submitting it as an example would not reproduce the issue. However, I've exported both markdown and PDF for review including embedded content to hopefully accurately portray at least the amount of content this object has in it. PDF is attached, whereas a .zip of the markdown export is here: https://drive.google.com/file/d/1Z\_5gIy-rkjoPcPm-\_WRouNlMskwZ-O7N/view?usp=sharing

I would love to see Capacities further its journey into performing better at these long-form objects that, in my opinion, aren't actually all that long form but utilize Capacities great organizational and formatting features.

And for what it's worth, here's my typical viewport when I'm working or running my game
