Release with the issue:
HA: 2025.6.3, sankey-chart 3.9.3

Last working release (if known):
This feature never worked for me

Browser and Operating System:

Win 10, Edge Version 137.0.3296.93 (Offizielles Build) (64-Bit)
iOS 16.6.1, Safari (?), Chrome and more
-> Basically all browsers on all systems I use

Description of problem:

The "entities" obtject has a tap_action parameter.
According to the documentation: "supported action types are 'more-info', 'zoom', 'navigate', 'url', 'toggle', 'call-service', 'fire-dom-event'.
I would love to use the 'zoom' type, expecting it would make the tapped entity the topmost one and thus focussing and enlagring all the children below.
Unfortunately this type never worked for me :-(
So is it supposed to work (with I would highly appreciate) or is the documentation just outdated.
I already looked into the code (only beeing a c# programmer though) and there seems to be some provisioning for it there...

Thanks for fixing it, as this would allow for very cool interactive dashboards.
And by the way thanks for this extremly usefull custom card in the first place.

Javascript errors shown in the web inspector (if applicable):

It works. I guess the syntax is not clear if you don't start from the UI editor.

tap_action:
  action: zoom
