It seems the
layerX/layerY
is unexpected in the case where the chart uses SVG renderer and has shadow filter.From the above picture, we can see that the values of
layerX/layerY
(unexpected) are not the same asoffsetX/offsetY
(expected) and don't look like the offset relative to the "closest positioned element". (I couldn't know the reason)According to CANIUSE and the release note of Firefox, the
offsetX
andoffsetY
have been supported since desktop Firefox 39And they have been also supported by Firefox for Android and Firefox OS since v43
As mentioned above, I'd like to use
offsetX/offsetY
for modern Firefox.A reproducible demo:
In addition, if we change to use
offsetX/offsetY
, it will make the feature mentiond in #794 possible.
