Emmet slow in large files

[SaniJasi]

I have a project on Shopify. And for developing I use files like this styles.scss.liquid.
And emmet working bad...
For example, I want to create font-size: 20px;
I use fz20 and press tab, but emmet generates font-size: 2px; but i need font-size: 20px;
And emmet working slow, please look this video: http://take.ms/kxnE

• VSCode Version: Latest
• OS Version: MacOS

Steps to Reproduce:

1. fz20 -> font-size: 2px; (this bug in all files scss, sass, less, css)
2. http://take.ms/kxnE

Does this issue occur when all extensions are disabled?: No

In your video, fz20 gets expanded to font-size: 20px and not font-size: 2px.
The slowness is due to the large size of your file. In the video, you have already crossed 10000 lines.
Do you see slowness in smaller files too?

The slowness of emmet in large files is being tracked in #43470

In my video, i recorded only slowness

Do you see slowness in smaller files too?
No

Can you share a video that shows fz20 expanding to font-size: 2px ?

http://take.ms/wIbDE you can see this bug also in this issue #38493

Looks like at second 8, we have w10

You add the next 0 and you hit tab to select the completion item before the auto-completion gets updated (because it is slow)

Fixing the slowness will fix this as well.

Will close this issue in favor of #43470

@SaniJasi This is fixed with 91416ff and the fix will be available in tomorrow's Insiders build.

Note to verifier:

• In a large css file (try more than 10k lines), type fz2
• Once completions show font-size: 2px, quickly type 0 and then tab
• In Stable (1.21), you will see font-size: 2px; and in Insiders (1.22) you should see font-size: 20px;
