Using grouping and date filtering causes graphs to shift left and cover parts of the page

[dschwentker]

Steps to reproduce:

1. Use IE
2. Add at least one y-axis grouping.
3. Change the Start Date

Chart should then jump to the left and cover the left hand menu options.

Test notes

• In CAT render the clinical-timelines.
• Narrow the time range.
• Verify the marks do not display outside of the chart.
• Render the clinical-timelines
• Narrow the time range.
• Verify the marks do not display outside the chart.

Issue was that the clip-path of the marks was set to url(#1) rather than to the ID of the chart. When a new chart is rendered the ID of the chart increments and the previous clip-path no longer targets the current chart.

This is most egregious in IE, but its actually occurring in a much more subtle manner in Firefox and Chrome as well, but it's only shifting over enough to cover the participant IDs, it doesn't jump all the way to the left hand side of the page. (As such, I've edited the title of the issue a little bit.)
