+
+;; Copyright (C) 2024-2026 Craig Jennings
+
+;;; Commentary:
+;; wttrin--reset-font-height re-applies the base wttrin-font-height, used for the
+;; loading placeholder so it does not keep the previous weather's auto-fitted
+;; (possibly capped) size.
+
+;;; Code:
+
+(require 'ert)
+(require 'wttrin)
+(require 'testutil-wttrin)
+
+(ert-deftest test-wttrin--reset-font-height-normal-restores-base ()
+  "Normal: resetting restores the applied height to the base wttrin-font-height."
+  (with-temp-buffer

+    (setq-local wttrin--current-font-height 200)
+    (let ((wttrin-font-height 130))
+      (wttrin--reset-font-height)
