## Problem
I tried to reproduce here, using multiple dates, and inserting code fences blocks, but it didn’t reproduce until
[https://try.discourse.org/t/testing-insert-date-bug/1130/2](https://try.discourse.org/t/testing-insert-date-bug/1130/2) (this link will become obsolete by tomorrow, but it shows like the screenshot above.)
## Cause
Finally I found the cause of the bug: the failing render follows an HTML tag with an attribute!
```markdown
in CommonMark](https://talk.commonmark.org/t/abbreviations-and-acronyms/890). 🙂
I suppose that an HTML tag appearing in a previous paragraph should not affect rendering later on though.
**In any case: when things fail, check for a mix of HTML and Markdown.**

Why do you need to use an emoji arrow? Use →

I simply pasted the result I got from using the ‘Insert Date’ button. The emoji transformation must be part of the cooking.
Edit: here is pasted the original character ➡ (or `➡` with backquotes)
Edit:
```ruby
'➡'.unpack('U*')
=> [10145]
```

Yes `➡` will be cooked as an emoji
I will give it a look to this tomorrow.

这实际上与 insert-date 无关。这是 `textPostProcess` 的一个限制。
例如，它在使用分类时也会失败，第一个会正常工作，但 `abbr` 之后的任何内容都不会（正如 @sam 提到的）：
* * *
#Contribute > Feature
`A`
A
#Contribute > Feature
* * *
我的理解是，`abbr` 之后的下一个块会被转换为段落，而不会被 `textPostProcess` 解释。这是我们的沙盒器（sanitizer）的行为，参见 [https://github.com/discourse/discourse/blob/master/test/javascripts/lib/sanitizer-test.js.es6#L117：](https://github.com/discourse/discourse/blob/master/test/javascripts/lib/sanitizer-test.js.es6#L117%EF%BC%9A)
@sam 有什么想法吗？你觉得值得修复吗？在我看来，这似乎是一个非常非常边缘的情况。

Something is not right internally cause `` does not cause this issue nor does `` or `` or ``
I am guessing this is something internally is broken in sanitizer that is specific to this inline tag. Probably worth fixing.
