Crashes caused when using lots of HTML + snippets

[ElianaTroper]

I am getting a crash consistently across files when using large chunks of HTML. When additional HTML is added via snippets, it causes a crash.

Example code before crash:

                                                Hi!
Helloworld.

Then when I add certain code via snippets, a crash is caused. Here is an example snippet that causes a crash (the crash is triggered when modifying the first highlighted portion of the snippet):

'.text.md':
  'Highlight and color text':
    'prefix': 'highlightcolor'
    'body': '<div style="background-color:${1:black};color:${2:white};${3:display:inline-block}">$4</div>

Typing out the same code or copy-pasting seems to cause no issue. I disabled all Markdown related packages when testing this besides this one.

I've been able to replicate the issue

• create a new document
• add the text from op:                                                 Hi!Helloworld.
• trigger the snippet
• type red where black is highlighted in the snippet

after the first two letters, re, Atom freezes for me, without any output in the console.

It seems to disable syntax highlighting

This isn't an issue. There's a limit on how many subsequent tokens are 'allowed' on a single line. I believe the default is 100. After that, syntax highlighting is disabled for better performance.
