Trying to figure out why completions within a snippet are not triggering until I ‘exit’ the snippet. For example, given a test snippet:
<snippet>
<content><![CDATA[
$1
]]></content>
<tabTrigger>test</tabTrigger>
</snippet>
I activate the snippet as expected with test->tab. Then, I immediately try to activate any other snippet/completion while ‘in’ the $1 stop and nothing happens. 
If, instead I hit enter thus ‘exiting’ the $1 stop, snippet/completion triggers now work.
