http://trac.tiddlywiki.org/ticket/1151
When a popup link is placed inside a DIV with style "overflow:scroll" or "overflow:auto" and that DIV is then scrolled, the position of the resulting popup appears further down the page that intended, because it is not adjusting for the relative scroll offset of the containing DIV. This tweak patches the Popup.place() function to calculate and subtract the current scroll offset from the computed popup position, so that it appears in the correct location on the page.
Test case: //(scroll to the bottom of this DIV and click on "test popup")//

/***
http://trac.tiddlywiki.org/ticket/1147
when the {{{<<tiddler SomeTiddler>>}}} macro is handled, the resulting span has extra attributes: {{{refresh='content'}}} and {{{tiddler='SomeTiddler'}}}. If SomeTiddler is changed, {{{store.notify('SomeTiddler')}}} triggers {{{refreshDisplay()}}}, which automatically re-renders transcluded content in any span that has these extra attributes. However, when additional arguments are passed by using {{{<<tiddler SomeTiddler with: arg arg arg ...>>}}} then the resulting span does NOT get the extra attributes noted above and, as a consequence, the transcluded content is not being refreshed, even though the underlying tiddler has changed
To correct this, in {{{config.macros.tiddler.handler}}}:
*set the 'refresh' and 'tiddler' attributes even when arguments are present in the macro
*store the arguments themselves in an attribute (e.g, 'args'), using as a space-separated, bracketed list
Then, in {{{config.refreshers.content}}}:
*retrieve the stored arguments (if any) and the tiddler source
*substitute arguments into source and re-render the span with the updated content
