Set maximum width on 'Filter by Phenotype' drop-down menu

[jseager7]

The 'Filter by Phenotype' field in some annotation sections has no maximum width configured, meaning its width is dictated by the names of the phenotype terms. This means that the phenotype filter can become too wide in some cases.

For example, on the gene page for PHIG:297, the phenotype filter is so wide that it overlaps the 'Expand all' button:

Here's the same image with the phenotype filter hidden:

The width of the phenotype filter should never become so wide as to overlap other UI elements.
