Actionlistops subfilter in TW 5.2.1 and TW 5.3.5 Works Differently

[kookma]

In Gatha plugin I have a macro as below:

\define add-by-filter-Button()
<$list filter="[subfilter{$(tempTid)$}] :filter[has[title]]  +[limit[1]]" variable=null>
<$button class="tc-btn-invisible" tooltip="add bulk of tiddlers to target plugin">{{$:/core/images/clone-button}}
<$action-listops $tiddler={{!!target-plugin}} $field="extra-tiddlers" $subfilter={{{ [<tempTid>get[text]] }}} />
</$button>
</$list>
\end

Note to <$action-listops $tiddler={{!!target-plugin}} $field="extra-tiddlers" $subfilter={{{ [<tempTid>get[text]] }}} /> and specifically to $subfilter={{{ [<tempTid>get[text]] }}} this works fine as you can see in https://github.com/kookma/TW-Gatha/releases/tag/0.8.1 which uses TW 5.2.1.

The same code does not work in TW 5.3.5. I hade to change the code as below

\define add-by-filter-Button()
<$list filter="[subfilter{$(tempTid)$}] :filter[has[title]]  +[limit[1]]" variable=null>
<$set name=bulktids filter={{{ [<tempTid>get[text]] }}} >
<$button class="tc-btn-invisible" tooltip="add bulk of tiddlers to target plugin">{{$:/core/images/clone-button}}
<$action-listops $tiddler={{!!target-plugin}} $field="extra-tiddlers" $subfilter="[subfilter<bulktids>]" />
</$button>
</$set>
</$list>
\end

Note again to $subfilter="+[subfilter<bulktids>]"

I wish to know what has happened to $action-listops and $subfilter from TW 5.2.1 to TW 5.3.5, so I can revise my other codes.

Thank you

More explanation: The macro add-by-filter-Button reads a filter from a searchbox (uses tempTid tiddler) and checks if filter returns any results, then add them to a field called extra-tiddlers in a target plugin tiddler.
