This is not a bug. \[...\] and \(...\) are inline elements within
a paragraph. However, \begin{...}...\end{...} environments are blocks,
and they break paragraphs. IOW, you cannot nest them.
The following should work however
\(
\left|\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}\right|
\)
because \begin{matrix} doesn't start the line, and therefore is not seen
as starting a new LaTeX block.
As a rule of thumb, Org has limited support for raw LaTeX in a document.
This is not AucTeX. For specific needs, you may want to use LaTeX
blocks, i.e., #+begin_export latex...
