Steps to reproduce:
- Use Internet Explorer 11 at either Windows 7 or Windows 8.
- Go to https://commons.wikimedia.org/wiki/Special:UploadWizard
- Click on the "Select media files to share"
- Either click "Cancel", or select one of images and then select "Open"
- (Optional) Click "Add more files", and repeat step 4
- Labels disappear from the blue buttons, i.e. blue buttons become label-less. The buttons become labelled again when the page is refreshed/reloaded, but repeating steps produce the same results.
- At IE11, the blue buttons should remain labelled after being clicked.
