toolbar of TinyMCE multilanguage textarea not rendered correctly in new version of AdminThemeUikit with LanguageTabs

[yellowmastodon]

Tinymce sticky toolbar probably gets wrong position and width assigned when switching multi-language tabs. This results in toolbar rendered vertically on the left side of the screen. Tested with current master version of Processwire and this issue does not occur there.

TinyMCE Settings:

Editor mode: Normal editor
When to load and initialize the normal editor? Load editor when it becomes visible
I think it also happens with "Load editor when the page loads".

Steps to reproduce:

1. Install Processwire 3.0.251 with site-languages site profile
2. Change the field "body" to TinyMCE
3. Edit some page and switch body field's language tab

Versions:

AdminThemeUikit 0.3.6
Processwire 3.0.251
LanguageTabs 1.1.7
