Cannot shrink sidebar in LibreOffice 7 (Writer)

I routinely have the sidebar open to show styles and formatting but only need to see part of the style name to be able to select it. To save screen space, I narrow down the sidebar so that just the first few letters of the style name is showing. This is no longer possible in LibreOffice 7 - there is a minimum size below which it cannot be narrowed and which is far more than I need with wasted space ++ on smaller screens. Is there a fix for this? Should I report it as a bug?

LO 7.0.3.1

In Tools>Options, LibreOffice>Advanced, Open Expert Configuration, I found a property set org.openoffice.Office.UI.Sidebar with subproperty *General containing a key/value pair MaximumWidth=500 but there is no MinimumWidth. The minimum may be either hard-coded or be an intrinsic limitation of the widget family used to implement the interface.

Seems to be addressed by bug report tdf#136764
