Fix "Hide lines" command hiding unselected lines issue 

To solve this issue, lambda removeMarker can be set to only remove just begin or end marker. By doing so, the process of merging adjacent hidden sections is limited and as a result, lines that shouldn't be hidden remain visible.

Fix #14166, close #14167
