• "DOWNLOAD" doesn't work on Edge/Win10
• Rendering issue on FF/[macOS|Linux]: only 4 codes show/column even though there were 5 in source (the overflow: hidden on the supporting-text class is cutting them off)
• IE11/Win10, renders codes in a single column always, printing and data: url don't work

before merging sil-org/ssp-base#47:

1. disable print and download for ie11/win10 with unsupported message on hover

3. troubleshoot flexbugs on ff and see if it helps with the rendering issue on ie11 as well.
