Winbar UI inconsistent with multiple tabs

[qgates]

Problem

When multiple tabs exist, :set winbar=%f%m the winbar doesn't appear on unfocused tabs.

Steps to reproduce

• open nvim
• create tab with :tabnew
• switch to the first tab with :tabp
• :set winbar=%f%m
• switch to second tab with :tabn

Expected behavior

Winbar should appear on all windows of all tabs

Neovim version (nvim -v)

v0.10.0-dev-3078+g3a8265266

Vim (not Nvim) behaves the same?

Also happens with disabling global 'winbar':

setglobal winbar=%f%m
tabnew
tabprev
setglobal winbar=
tabnext

Which causes the second tabpage to behave like there is a winbar even though it's disabled, and may leave redraw artifacts.
