Found a bug where the pop up box to share an attachment from a confluence page appears behind the greyed out modal of the attachment view. Under the input box there is a text box which contains the following code:
</div><div class="field-group button-panel"><div class="progress-messages-icon"></div><div class="progress-messages"></div><input class="button submit" type="submit" value="Share" disabled/><a class="close-dialog" href="#">Cancel</a></div></form>
Seems that was supposed to render the Submit and Cancel buttons?
