Missing pages when exporting note to PDF

Bug graveyard
1

Steps to reproduce

  1. Create a note that contains a large amount of Markdown and LaTeX (e.g., for recording math class notes).
  2. Switch to Reading mode.
  3. Export the note as a PDF.
  4. Observe that some pages or content are missing in the exported PDF.

Did you follow the troubleshooting guide? [Y/N]

Y
(Tested with default settings, no third-party plugins or custom CSS, default theme.)

Expected result

The exported PDF should include all pages and render all Markdown and LaTeX content correctly.

Actual result

Some pages are missing from the exported PDF.
Additionally, the missing content appears as raw Markdown/LaTeX code in Reading mode rather than as rendered text.

Environment

Obsidian version: 1.9.14
Installer version: (latest)
Operating system: Windows 11 / macOS (tested on both)
Vault: default settings, no plugins or CSS snippets

Looking at a part, it appears large sections aren’t rendering in Reading view because of the <br> tags. The Untitled note here (without a line break after the <br>) will create a blank PDF.

If you need to keep all the <br>s in there, add a blank line below them and any other content. e.g.

#### 易混淆的点：
$$\lambda = \frac{h}{p} = \frac{6.626 \times 10^{-34} \text{ J}\cdot\text{s}}{1 \text{ kg}\cdot\text{m}\cdot\text{s}^{-1}} \approx \mathbf{6.63 \times 10^{-34} \text{ m}}$$
物质的波长非常小($6.63 × 10^{-34}$), 但是这不意味着物质能量很高；只有光子(无质量粒子)的能量是和波长有关的。而根据公式$K = \frac{1}{2} m v^2$ 和 $E_0 = mc^2$ 物质的能量和质量有关，在这种情况下，**波长 $\lambda$ 极小** ($\approx 10^{-34} \text{ m}$) **的原因仅仅是因为其质量 $m$ 极大(1kg)**

##### 为什么宏观物体的质量 $m$ 是导致其德布罗意波长 $\lambda$ 极小
<br>

1. 根据宏观物质动量公式：
$$p = m \cdot v = (1 \text{ kg}) \cdot (1 \text{ m}\cdot\text{s}^{-1}) = 1$$
2. 将数值代入德布罗意公式：$$\lambda = \frac{h}{p} = \frac{\text{极小的数} \quad (6.626 \times 10^{-34})}{ \text{相对大的数} \quad (1)}$$$$\lambda \approx 6.63 \times 10^{-34} \text{ m}$$

got it, thank u
