Comment:

 Sorry, the [https://wordpress.org/support/forums/ support forums] (or
 ''WordPress.com'' support) probably would have been more helpful. And now
 few people use Internet Explorer anymore.

 I can set the background color and use the menu at various widths with
 Twenty Fifteen and no plugins. So I'll close the ticket as "works for me."

 However, the problem (still) can occur on your site in IE 11 at smaller
 window widths. This seems to be related to a custom colors plugin, and
 maybe another. The custom background color does not work because a script
 is supposed to add a `small-screen` body class when under 955 pixels. The
 menu does not expand, but I do not have console errors to explain why.

 If you already have access to the "Additional CSS" feature under
 Appearance, you could try adding this for IE users:
 {{{
 @media all and (max-width: 954px) and (-ms-high-contrast: none), (-ms-
 high-contrast: active) {
         .sidebar .site-header { background-color: #202020; }
         .sidebar .secondary { display: block; background-color: #202020; }
 }
 }}}

 Otherwise, you could try deactivating certain plugins and/or contacting
 support.
