The simplified issue

I have a svg embedded in another using a object tag that is contained in a foreignobject as per recommendation by mdn to retain script execution.
The inner eventlistener (green in second.svg) doesnt do anything in webkit while chrome and firefox have no problem with this.
The outer eventlistener (pink in main.svg) works though.
Because I am able to call the alert from main.svg even when the website is embedded into HTML via object tag, I concluded that the object tag cant be responsible.
My guess is that it is the foreignObject tag.

I have uploaded the issue to github pages to spare you the download of the attachment: https://scopeofaperture.github.io/safarisvgissue/

If this is expected behaviour please tell me and if you have, please point me to documentation mentioning this.
