This behaviour was removed by design. For "casual" visitors of your page it
created a very unexpected behaviour. eg: They wanted to "double-click mark
content" to copy paste it. When the editor opened, they thought, they broke
the internet / web page ;)

The rendered HTML text has no knowledge where it came from eg:
Some text
{{myText}}
may be rendered as
Some text
Some more text
So what should clicking Some more text, do now? ...
Either open the tiddler named: myText or edit the tiddler which is actually
open? ... Whatever we implement will be wrong. ...
So it'll need to be adjustable or ctrl-Dbl-Click vs Alt-Dbl-Click .... or
what ever.
... BUT ...
The bigger problem is. Some more text doesn't know, that it belongs to myText
tiddler.
The possibility of transclusions, lists and so on, makes it *really hard*
to calculate the position in the source text, based on the rendered cursor
position.
"really hard" as in:
- We need to extend the functionality of the "wikitext parser", that it
stores source positions of every element in TWs internal structure: the
"parse-tree".
- The parse-tree is converted into the widget-tree, which also needs to
deal with this new info now. ...
- The renderer, which uses the widget-tree needs to write this info into
the html-output.
- The navigator-widget finally has to deal with the new "double clicks"
to open the corresponding tiddler + selecting the right position in the
source code.
Which basically means "rewriting" most of the parsing -> rendering
pipeline. ..
IMO it still is an interesting idea, since we could make some other
improvements along the way. Eg store the tiddler content in a different
format and *partially *convert TW syntax -> markdown -> TW syntax. ....
I have recently created a Tag that once added to a code tiddler Displays
