<div style="d|"></div>

In the above case, there are no suggestions from the emmet completion provider.
Css abbreviations should be suggested.

In the latest Insiders it is possible to get css emmet completions inside the style attribute but only if there is a space after the "
<div style=" dn| "> would give the right completion i.e display: none
but <div style="dn|"> wouldn't give any completion

This is because we assume that current word is the abbreviation in case of css. With emmetio/extract-abbreviation@ee01c36 we can use the extract-abbreviation module to fetch the abbreviation correctly
