Created attachment 466241 [details] SVG showing artifacts after moving element When a drop-shadow filter is attached to a group, and an element inside that group moves, it leaves artifacts. A minimal reproduction is provided in https://jsfiddle.net/highcharts/rhgksLtw/ and in the SVG attachment. First reported to Highcharts: https://github.com/highcharts/highcharts/issues/18927

I am able to reproduce this bug using WebKit ToT (263785@main) using attached test case. Chrome Canary 115 does not have any artifacts and I think it is more an issue with Layout & Rendering rather than SVG. CCing - Alan to get his input on Layout & Rendering being source issue here or it is just SVG issue?
