为什么添加 hyperref 会导致 algorithm2e 不再跨页面？

Question

TL 2020. 使用编译lualatex

我已经设置了表格

 \begin{algorithm}[H]
    ....
 \end{algorithm}

 \begin{algorithm}[H]
    ....
 \end{algorithm}

 \begin{algorithm}[H]
    ....
 \end{algorithm}

如果没有它，编译时也\usepackage{hyperref}可以正常工作，并且所有算法都不会尝试适应单个页面。

添加时\usepackage{hyperref}，所有算法都尝试放入单个页面，但它们被截断了。尝试更改和的顺序hyperref，algorithmic但没有任何变化。

我做错什么了吗？
