AFAICT not a recent regression of the text tool in Inkscape 0.92 (or otherwise related to changes in with regard to text formatting in Inkscape 0.92).
Reproduced with Inkscape 0.91 r13725 and 0.92.0 r15299 (on OS X 10.7.5) in a new document which uses a document scale other than px. In Inkscape 0.91, use for example 'default mm' from 'File > Templates', in Inkscape 0.92 the default template (now mm-based).
