Startify and vim-dirvish override statusline

[ghost]

• Startify will override statusline generated by el

  On initial nvim launch el generates statusline for startify's window correctly. But once another buffer gets opened and :Startify gets called it will revert to Startify's statusline: statusline= startify.

• vim-dirvish will reset statusline to empty: statusline=

  Exiting from Dirvish's buffer restores statusline from el.

Edit: same happens for nvim-tree.lua.
