Animations in background tabs

[petrklus]

I've got a few animations following one another. They work fine when I open the tab, however, when I open the tab in the background and switch to it later, I see that the animations overlap. After a few seconds, they "catch up".

Is this a known issue / something that has been observed before?

Just to add further note on this - the only way to ensure proper sequence is to use the end callback to launch further animations. The delay parameters cannot be relied on.
