I took a look at this with MCP-Reborn and found a solution for this bug.
In ReadBookScreen#render, the call to super.render is made after renderComponentHoverEffect which will cause the buttons to be render over the tooltip.
By moving the call to super.render above the renderComponentHoverEffect i solved the issue.
