Can't create images when using ${projectRoot} variable

[brendan33]

I am using VSCode in Windows using Remote SSH to connect to my project in a Ubuntu VM. When I set Paste Image Path to ${projectRoot} then the markdown is inserted but the image file is never created (I don't see any errors) If I paste the image using default settings of ./ then it creates the image file and inserts the markdown as expected.

I don't think it is a permissions issue because if I paste into a MD file in project root and use ./ then it creates the file ok.
