Julia 1.20 and PyPlot.svg(true)

on Windows 10 64, Julia 1.2.0, the following crashes jupyter 
```
using PyPlot
PyPlot.svg(true)
figure()
plot(1:10)
```

Without  ```PyPlot.svg(true)```, it works well. 

 
EDIT: "crashes" is perhaps too strong. But it unhinges and scrambles the jupyter menu so that it becomes useless.
