Bug Description

After the recent introduction of the PDF export feature, I noticed that LaTeX formulas are not correctly processed. Whether using inline math or math blocks, the equations either disappear completely or fail to render, leaving gaps or raw text in the final PDF document.

How to Reproduce

Steps to reproduce the behavior:

Open a page in AppFlowy and insert an inline formula (e.g., E=mc^2) or insert a math block with a complex equation (e.g., E=mc^2).
Go to the menu and select Export to PDF.
Open the generated PDF file.
Observe that the mathematical expressions are missing.

Expected Behavior

The exported PDF should render LaTeX formulas as high-quality mathematical symbols, maintaining the same visual consistency seen within the AppFlowy editor.

Operating System

Windows 11

AppFlowy Version(s)

0.11.1 (Official build)
