Items disappearing, some partly, some completely [Safari and iOS]

[dmbjsn]

Hi,

While I like this plugin, I have found a rather disturbing bug present in Safari and iOS Safari.
On render, the circle looks fine, but on hover, positions (indexes) 4 and 9 disappear completely or partly. This also happens with the official demo, so you can try it yourself.

Does anyone have an idea what's going on here? Nothing on Chrome.

I can confirm the bug, but don't have any idea why it happens and how it can be fixed. Please share your solution if you find one.
