Markdown All In One breaks Math block syntax highlighting

[bhuynhdev]

Problem

After I installed the "Markdown all in one" extension in VsCode, the enclosing highlighting of math block is not working correctly any more. Removing the extension and the highlighting works again, so I figured I would make an issue here.

As seen in the image, the "$$" signs at the end of the Math block is understood as something different. Therefore, subsequent markdown is not highlighted correctly, even though they are rendered correctly.

Other features of Markdown All in one still works, including Latex autocomplete/Intellisense inside the math block.

Configuration

No other extension (such as Markdown+math) were installed. I tried turning off the "math.enabled" option, but it didn't resolve the issue. Assigning the value to true also did not resolve the issue.

"markdown.extension.math.enabled": false

Environment

Lubuntu 20.04
Markdown all in one 3.4.0 (should be the newest version because I just installed it through VsCode Market 5 min ago)
VsCode 1.60.0

Diagnostic data

There seems to be nothing in the Debug Console

Conflict with VS Code's built-in Markdown Math (vscode.markdown-math) extension.

We both inject TM grammar for the same (at least similar) thing:
https://github.com/microsoft/vscode/blob/4e37c907d238758879047c4218756ff5d99dae82/extensions/markdown-math/package.json#L33-L59

vscode-markdown/package.json

Lines 500 to 519 in f67fa77

	"grammars": [
	{
	"scopeName": "markdown.math_display",
	"path": "./syntaxes/math_display.markdown.tmLanguage.json",
	"injectTo": [
	"text.html.markdown"
	]
	},
	{
	"scopeName": "markdown.math_inline",
	"path": "./syntaxes/math_inline.markdown.tmLanguage.json",
	"injectTo": [
	"text.html.markdown"
	]
	},
	{
	"scopeName": "text.katex",
	"path": "./syntaxes/katex.tmLanguage.json"
	}
	]

The merge result is unpredictable.

contributes.grammars is a "declarative" thing in VS Code's world. The only way to remove it is disabling the corresponding extension.

I'm sorry that you have to disable one of them.

Thanks. Disabling the builtin Markdown Math (as shown by @yzhang-gh) did work. Now the math blocks gets separated correctly. I think this is something that should be stated in the documentation.

Done.

Today I ran into this problem too.

The method here works fine but need to disable the builtin markdown-math plugin. I accidently find another solution. Here it is:

$$f(n) = \begin{cases}
0, & n = 0; \\
1, & n = 1; \\
f(n-1) + f(n-2), & n > 1
\end{cases}$$

just not add newline after open $$ and before closing $$. Then highlight works fine.

While this method may looks ugly... Just for a record here.
Anyway, I will disable the builtin one.

我觉着可以给出一个选项，单独关闭 markdown all in one 的数学高亮。两个插件的数学高亮还是有区别的，比如行内公式，markdown all in one 无法识别$号前有空格的情况：

而内置插件可以：

或者是调整一下识别行内公式的方法。
