Dropdowns shift after expanding

[progers]

On the paper dropdown demo, the dropdowns will move around after they have expanded. This is different from #130 where the scrollbar disappears, as it's the actual popup that's moving. This may be related to non-overlay scrollbars which are the default when a mouse is plugged in.

I've attached an exciting movie showing this behavior.

I believe it readjust itself to match the position of the container which shifts when scrollbars disappear

Seeing this too for the IO site. Every use of paper-dropdown-menu is doing this. The most violent is our top nav.

On first open, the dropdown adjusts itself. For subsequent opens, the positioning is fine.

Note: if no-animations is used, there's no jitter adjustment.

If animation is disabled then there is no shift

Looks very similar to PolymerElements/iron-dropdown#69

Do you guys have iron-dropdown v 1.3.0?

Pulled down the latest releases and it seems to be gone!

yay! closing this.
@progers @miztroh LMK if this is still an issue for you, and I'll reopen again ;)
