Created attachment 471796 [details] Example code Conducting some tests using Safari Technology Preview, I observed that creating a canvas using `document.createElement("canvas")` does not allow `ctx.filter` to work properly. Setting `ctx.filter` always returns `none`. This issue only occurs if the canvas is not added to the HTML page body. Expected Result: The filter should be applied to the canvas regardless of whether it is appended to the document body or not, applying the filter even when it is an SVG filter. Actual Result: In Safari, setting a filter on a CanvasRenderingContext2D where the canvas is not part of the document always keeps the filter as none. When the canvas is appended to the document before setting the filter, everything works normally.
