Created attachment 129339 [details] screenshot See the attached image. loolwsd-1.9.10. Steps to reproduce: 1. Just open a one page document 2. Click Insert comment in the toolbar.
I'm marking it new but it does not show with LOOLWSD 2.0.0 (git hash: 1ed0527) LOKit Collabora Office 5.1-14 (git hash: fe87a31) So it may be also a worksforme if you can upgrade.
I confirm this is fixed in 2.0.0.
