*-start/*-end placement with followCursor option reversed + incorrect offset (v4.3.2)

[lozinsky]

Bug description

Thanks for the backport v5 fixes to v4 (#511).
In the case where the placement option has *-start/*-end value and followCursor option is defined, tippy is placed on the other side of the cursor in 4.3.2 version. Is this a new expected behavior or bug?

I think it's actually correct now. Before, the virtual reference had zero size but now it actually has a "fake size" of 100 pixels which prevents some issues. It looks like that ended up reversing the behavior though.

Though it does seem to be offset by 8 pixels now, so there could be something wrong here.

If you add arrow: true and comment out followCursor: true, you'll see the placement seems to actually be correct in 4.3.2. But I don't know about the slight pixel offset now.

If I want tippy to be near the cursor as in version 4.3.1 I need to add offset: "50, 0"?

I think the reversement of placement is correct now (although kind of a breaking change from previous behavior? 😕), but the offset problem is a bug. It changes based on the tooltip element's size.
