Comment (by mdgl):

 I get a slightly different error in this situation (code CSS3111 rather
 than CSS3113):

 {{{
 CSS3111: @font-face encountered unknown error.
 dashicons.eot
 CSS3120: No fonts available for @font-face rule
 load-styles.php (0,37)
 }}}

 Despite this, the dashicons appear to display correctly, even though Edge
 seems to think there is something wrong with the font file.  Perhaps this
 ticket needs to be re-assigned to a different component?

 Descriptions of the two relevant errors from Microsoft are:

 ||= Code =||= Message =||= Description =||= Suggested fix =||
 ||CSS3111||"@font-face encountered unknown error"||An unknown problem was
 encountered with the "Web Open Font Format (WOFF)", and "Embedded OpenType
 font (EOT)" of the Cascading Style Sheets (CSS) font.||Check source of
 "WOFF" fonts. Try alternate font face or source to see if problem
 reproduces.||
 ||CSS3113||"@font-face mismatch between document origin and EOT root
 string"||The font cannot be used because the URL(rootstring) in the
 "Embedded OpenType font (EOT)" does not match the domain of the document
 using the font.||The URL checksum in the "EOT" rootstring might be
 incorrect, indicating a corrupt or altered URL for the font. Ensure that
 the font is licensed or has permissions for the website where the fonts
 are being used.||
