Apple Books' Intensive CPU Usage

A process from Apple Books, com.apple.WebKit.WebContent is using the CPU around 99%. To the point of my mac eventually becomes warm. This doesn't make sense if reading a single book consume 99% of the cpu how would I even work? I am reading a downloaded epub Book with Apple Books on macOS 13.4 and the cpu usage is insanely high. It would be great if someone can help me with this. Thanks.

MacBook Air 13″, macOS 13.4

Just had a similar issue on IPhone 13.

While reading a book, with no other apps open, my IPhone got warm and started draining battery - about 10% for 30min. of reading.

P.S. Was advised by Apple Support that uninstalling and reinstalling the Books app might solve this.
