Rate coefficient plot isn't being diplayed when many sources are available

[alongd]

Searching for reaction kinetics for [CH3] + [CH3] gives 66 results (most are R_reccombination/NIST), and the plot shows only the long legend, and is unreadable.

This is very inconvenient behavior, but it also seems to be system dependent.

• Firefox on Windows shows the above behavior
• Chrome on Windows reduces the height of the plot, but it is still visible
• Chrome and Safari on Mac both show the full plot without any interference from the legend
• Chrome and Firefox on Linux both show the full plot as well

Unfortunately, this is probably not helpful for users who only have access to Windows, but the solution would require looking into the Highcharts JavaScript package that we use to plot.
