[InlineShareButtons] buttons disappear when element layout occurs
I've got a very basic usage of the buttons but whenever the page layout changes some buttons disappear.

you can see here I'm reloading then resizing the window
I wasn't able to reproduce the error, could you provide more specifics if you still have that problem?
I am also facing the same issue when there is layout changes button disappear
We have the same issue even on a plain HTML page without a specific JS framework in place. Resizing the window or switching from portrait to landscape mode on a mobile devices make the buttons disappear.
Same here. Probably also the reason why some buttons don't appear from the beginning unless I add more, there's some layout shenanigans going on
For us the issue was that we changed the spacing between the buttons in our CSS, but in the libraries resize handler it calculates the required width based on the width + offset given in the button configuration. To fix it we added a fixed width to the sharethis-inline-share-buttons class and now the buttons stay where they are. Maybe this information will help someone.
