Annotation sidebar settings is not working from a second editor. If field is under tab

Hi @jkamizato
Thank you for bringing this issue to our attention. We'll check the issue soon and notify here once we have a solution.
I have a question - are you positive that you're using version 1.2.5? In this release we introduced an update to the editor wrappers structure. Toolbar should actually now span over whole editor element (editing area and sidebar). I wonder if your screen was made with older version or is it another bug raleted to tabs.

We had actually worked on fieldgroup tabs support before. However we only considered auto sidebar mode (based on viewport width).
For now I simply added handling of fixed sidebar modes within tabs.
I think we may need to change this to monitor editor visibility in general and apply proper methods once editor becomes visible for user (as this is potential issue for modal windows and custom made tabs which contains editor with sidebar).

As for now I'm attaching a patch which adds support for fixed mode sidebars in fieldgroup tabs which should work for your site.

Thanks @salmonek! Patch in #5 fixed the issue.

We have released 1.2.6 with update which should work for all cases where editor is initially hidden (not limited to field group module).
The #5 patch isn't compatible nor required in 1.2.6
