I had a look at the reports. A point which might be important: you quoted the version information AFTER the fix. VCL= displays gtk3 whereas initially (with the issue) it was qt5 which ringed bells in my head. Developers may not be able to reproduce the problem with gtk3 which IMO is the base widget library used to develop LO, i.e. the most checked, debugged and observed interface, in other words deemed reliable.
You should add a remark about it.
