Summary

Upon inspecting the EPUB renderer, it was clear the height styling was not functioning as it was originally intended. This was abundantly clear based off the positioning of the left/right buttons, not being centered. The issue appeared to originate from some alterations to the flexbox structure upwards in the DOM. By relocating a newer div wrapper used for applying a relative style, this removed the interference causing the malfunction, and restored the intended styling.

This does not address the tagName error linked in the issue as it's wholly unrelated to the render issue, and possibly benign.
