Some environment variables missing

[cinghiopinghio]

Describe the bug In practice the environment variable QT_QPA_PLATFORMTHEME is not set inside nvim-gtk while it is set outside to qt5ct (!echo $QT_QPA_PLATFORMTHEME return an empty string). Other environment variables are set as expected.

Technical information (please complete the following information):

• OS: gnu-linux [arch]
• Neovim version:

  
  NVIM v0.3.5

Does it works inside console nvim? Does it works when run nvim-gtk --no-fork?

[cinghiopinghio]

It does work in both cases.

I try run X=3 nvim-gtk and !echo $X works for me, so maybe this is some problems with specific variables? Maybe this is somehow depends on selected gtk theme and gtk do some manipulation with it
