Regression

Yes, after lua.

Describe the bug

Similar symptom as #14233.

When exiting fullscreen state of a tiled window, the borders are not redrawn.

hl.dispatch(hl.dsp.window.fullscreen({ mode = "fullscreen", action = "toggle" }))

Reproduction steps

1. Open two windows tiled on a workspace
2. Fullscreen one window
3. Un-fullscreen that window
4. Borders are missing.

NOTE: Similar to #14233, grabbing the window with the mouse is enough to jigger the redraw of borders.

Again, this is with "Smart Gaps" example enabled:

Hyprland/example/hyprland.lua

Lines 163 to 179 in bd7f695

	-- Ref https://wiki.hypr.land/Configuring/Basics/Workspace-Rules/
	-- "Smart gaps" / "No gaps when only"
	-- uncomment all if you wish to use that.
	-- hl.workspace_rule({ workspace = "w[tv1]", gaps_out = 0, gaps_in = 0 })
	-- hl.workspace_rule({ workspace = "f[1]", gaps_out = 0, gaps_in = 0 })
	-- hl.window_rule({
	-- name = "no-gaps-wtv1",
	-- match = { float = false, workspace = "w[tv1]" },
	-- border_size = 0,
	-- rounding = 0,
	-- })
	-- hl.window_rule({
	-- name = "no-gaps-f1",
	-- match = { float = false, workspace = "f[1]" },
	-- border_size = 0,
	-- rounding = 0,
	-- })

Gaps (inner/outer) also don't reappear after un-fullscreening:
