Jump sequence for placeholders in yasnippet not working in org-property blocks

Question

I use the yasnippet bundle and it works like charm.

When I want to include placeholders in a PROPERTIES section of an org-document it is not working.

Here's the snipper:

#type: snippet
# --
:PROPERTIES:
${1: :var: name="$2"}
${3: :var: url="$4"}
:END:
$0

What this does is to define 2 optional variables, "name" and "url".

When calling (yas-tryout-snippet) on the snippet above, the cursor is not positioned correctly.

Here where it should jump:

Press tab 1st: Make whole line ${1: :var: name="$2"} because it can be optional

Press tab 2nd: Make only "$2" in the line ${1: :var: name="$2"}.

Press tab 3rd: Make whole line ${3: :var: url="$4"} because it can be optional

... and so on

Here's what it actually does:

Press tab 1st: Make whole line ${1: :var: name="$2"} because it can be optional

Press tab 2nd: Make whole line ${3: :var: url="$4"}

---

The problem seem to be produced by the :var: Keyword.

It stops yasnippet from jumping to the $2. If I change it to only var: or :var it will work. But then it won't be able to include these properties into a src code block and work with it. It will also work if I remove the quotes from the placeholder. So this will work, but as before, then I cannot eval the url var in code blocks

${3: :var: url=$4}

I also tried excaping things with no luck:

${3: :var: url=\"$4\"}
or
${3: :var: url='$4'}
or
${3: \:var\: url="$4"}

Any ideas on how to write this snippet or what I'm doing wrong.
