     src/dispextern.h (struct bidi_it): New member disp_prop_p.
     src/xdisp.c: Remove one-slot cache of display string positions.
     (compute_display_string_pos): Accept an additional argument
     DISP_PROP_P; callers changed. Scan at most 5K characters forward
     for a display string or property.  If found, set DISP_PROP_P
     non-zero.
     src/bidi.c (bidi_fetch_char): Accept an additional argument
     DISP_PROP_P, and pass it to compute_display_string_pos.  Only
     handle text covered by a display string if DISP_PROP_P is returned
     non-zero.  All callers of bidi_fetch_char changed.
