描述问题 Describe the problem

预览模式下粘贴公式到公众号, 公式尺寸异常

  • 文档代码:
对 slimarray 中一段数据的求和运算会变得非常高效,
对n个数字yᵢ的求和可以转化为简单的数值计算:

$$
\begin{aligned}
\sum y_i = & \sum\beta_0 + \sumβ_1 i + \sum \beta_2 i^2 + \sum d_i \\
         = & \beta_0 n \\
      & + \beta_1 \frac{1}{2} n (n+1) \\
      & + \beta_2 \frac{1}{6} n (n+1) (2n+1) \\
      & + \sum d_i
\end{aligned}
$$

ok

  • 点击 预览 后可以正常渲染:

  • 点击 复制到公众号, 在公众号 图文编辑器中粘贴, 得到的公式很小:

在Chrome里提取的粘贴后异常的公式的html代码:

去掉width属性后,显示就正常了:

现在依然有此问题，部分公式会错位，暂时只能用 mdnice 了。
