Strange featureGroup behavior with svg icons (they are not displayed)

[victory-v]

Description

I added icons for markers as svg-code. Inside featureGroup icons aren't displayed on the map (while markers themselves are presented and svg-code is in the marker too). In the same time, in devtools I found strange div block inside the map with display:none styles with all my icons inside again. If I remove display:none, I can see all my icons.

Steps to Reproduce

Expected Results

I see marker's svg-icons inside featuregroup

Icons are not visible

@victory-v Thanks for the issue AND the codesandbox!

Will investigate!

@victory-v I've checked your codesandbox, if I remove some of the extra markup of the svg they show up:

The display:none is a trick that we use to feed leaflet the correct markup so you should not worry about it.

@DonNicoJs alright, I see that it doesn't work with all that filters but with normal fill or stroke attributes it works well.

@victory-v I suspect that this is more a leaflet issue than vue2leaflet, maybe you can try to investigate there.

But please let me know if you think is something related on how we handle the icon here in vue2leaflet!

@DonNicoJs in plain Leaflet everything was ok, then I switched to vue2leflet and faced this problem.
Actually without featureGroup everything is fine on my localhost but somehow I can't reproduce this in sandbox.

@victory-v Interesting, try to check if the version on codesabbox, locally are the same I recently released a fix for featureGroup ;)

[victory-v]

@DonNicoJs locally I had the same version 2.4.1, I updated to 2.4.2 but visually nothing changed

@victory-v mmh this is weird, if you find a way to reproduce this let me know
