From e9f1c086142c28abb54651c03f3345024d737d60 Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Sun, 30 Mar 2025 10:29:57 +0300 Subject: [PATCH] Fix display of overlay arrow immediately after invisible text * src/xdisp.c (overlay_arrow_at_row): Allow the overlay arrow's marker position to be anywhere between the row's start and end charpos. This keeps the overlay arrow on display even when the preceding text is invisible.
