Samsung Tab S3 with Keyboard case stops Chrome opening bookmarks page

[Android Central Question]

I have a Samsung S3 tablet and have just bought the Samsung original keyboard case for it. When I have the keyboard docked the bookmarks page in Chrome doesn't load unless I open a new tab or switch tabs. The bookmarks page opens fine when the keyboard is not docked. Any thoughts on how to stop this?
Chrome 66.0.3359.158
