HTL: "automatic" context=uri on href/src seems to be wrong - Should be uri *and* html

url=http://test.com/?a=true&b=false&c=%3F

<a href="${url}">Test</a>

I expect the href to be (when viewing page source):

http://test.com/?a=true&amp;b=false&amp;c=%3F

It however is:

http://test.com/?a=true&b=false&c=%3F

HTML requires attributes to also be encoded, so I believe we're not doing enough to do the proper encoding/escaping here.

WDYT?
