fix: tooltip container scroll issue #647

Summary

Fixes tooltip render issue

refactor tooltip logic to account for portal
separate tooltip and tooltip portal components
update tests to check for new portal condition
set max tooltip width from component js

fixes #596

Temporary fix

For really narrow charts where the tooltip cannot fit on the right nor the left, a temporary fix was added to limit the width of the tooltip portal to a max of 70% of the chart elements width to limit hiding the tooltip on the left. This is temporary until a more robust positioning logic is add in #651.

One issue with this approach is that the tooltip will go out of the element on the right for values in the center of the chart. However, this will not cause the scrollbars to show as described in #596.

This issue can also be seen with relatively normal widths where the tooltip portal does not fit in the space but the visible tooltip does, creating an unnecessary flip to the left side, which might cause the tooltip to appear outside of the element.

Root cause

Tooltips rendered towards the right edge of the chart container would compute if the tooltip "fits" based on the .echTooltip element and not the #echTooltipContainerPortal element. Notice the red bar rendered behind the tooltip as the #echTooltipContainerPortal element. Thus, when the .echTooltip element width is less than that of the #echTooltipContainerPortal the element will still render on the right but the #echTooltipContainerPortal created an invisible additional width that pushed the tooltip off the page.

The fix is to just account for the #echTooltipContainerPortal element width in the "fitting" calculation but still use the .echTooltip element width for final positioning.

This LGTM! Tested locally in Chrome - no scrollbar in the playground nor in the stories when squishing the browser.

I've checked in our storybook and also on the PR playground and it doesn't seem to solve the problems once for all.

on the playground, (treemap example) if you get rid of the legend the scroll bar will appear
the same happens on the storybook for treemap, see:

3) all charts are suffering from the same issue:

I've open a partial PR with a fix for horizontal charts: nickofthyme#1

Fixed annotation tooltips with the same fix as the regular tooltip.
