Board->Add List: label text colour remains black even if label colour is dark

Summary

When adding a list in Boards, if the label colour is dark, the label text shown in the list is colored white. However, adding that label will cause the label at the top of the list to show up as black. Refreshing the page will render the label text correctly to white.

Steps to reproduce

  1. Go to a Boards page
  2. Click Add list
  3. Select a label that has a dark background color (best if it's black)

To fix, refresh the page.

Example Project

(If possible, please create an example project here on GitLab.com that exhibits the problematic behaviour, and link to it here in the bug report)

(If you are using an older version of GitLab, this will also determine whether the bug has been fixed in a more recent version)

What is the current bug behavior?
