Build error with The name `enable_javascript_markup' does not exist in the context of `WebKit.Settings?' when trying to build for buster-backports

Hi,

I'm trying to build geary 3.34.1 for buster-backports. I was able to 
build 3.34.0 successfully, but now I'm getting this error with 3.34.1

../src/client/components/client-web-view.vala:310.9-310.38: error: The 
name `enable_javascript_markup' does not exist in the context of 
`WebKit.Settings?'

        setts.enable_javascript_markup = false;

I tried updating minimum versions of libwebkit2gtk-4.0-dev (>= 2.26~) 
and libjavascriptcoregtk-4.0-dev (>= 2.26~), but the error is still 
there. I had to relax dependency on gtk to build with libgtk-3-dev to 
3.24.5 and also meson. Any other libraries I should update?

Thanks

Praveen
