Display math in admonition

[tyl012]

Describe the bug

issue
I tried to put some content with display math inside an admonition block, but the output html form is incorrect.

Reproduce the bug

I tried to put the following content

A linear map $f:\mathbb{C}\to\mathbb{C}$ is of the form
$$f\left(z\right)=az+b$$
where $a,b\in\mathbb{C}$.

in an admonition block

```{tip} 
A linear map $f:\mathbb{C}\to\mathbb{C}$ is of the form
$$
f\left(z\right)=az+b
$$
where $a,b\in\mathbb{C}$.
````

However, the output in html file is apparently incorrect, comparing the upper part and the middle one in the screenshot

The indentation of the line following the displayed part is wrong, and strange spacing was added around the inline math.
The lower part of the screenshot shows a simple fix of the issue when I add a line before the double dollar sign of the display math (adding a line after the display math works equally well)

```{tip} 
A linear map $f:\mathbb{C}\to\mathbb{C}$ is of the form

$$
f\left(z\right)=az+b
$$
where $a,b\in\mathbb{C}$.
```
