Is your feature request related to a problem? Please describe.
At the moment, if the component is used in any of the following ways:

• width and height set
• fluid={false}

the component still takes two render passes to fully render, when it can be completed in one.

Describe the solution you'd like
Check whether either of the following are true and eagerly render if true:

• width != null && height != null
• fluid === false

This will be fixed in the next major version, v8.
