I think it is the same issue as was reported earlier, but it was closed without further comments: Twitter share button not working in IE and FF when within modal
- Go to https://notebooks.azure.com/
- Create a new library
- Click Share
- Click Social Media tab
If you were doing this in Chrome, you can see Tweet button. If you were using Edge (likely, in Firefox and IE too), you can’t see Tweet button, it is invisible.
You can find that tweet button using F12 Developer Tools.
Two things that prevent Twitter share button from being displayed:
- iframe’s width and height are both 1px
- div id=“widget”'s overflow is “hidden” (in Chrome, it I hidden as well, but it does not prevent the button from being displayed).
