App crashes when trying to move multiple selected lines up (Alt+Up)

Hi,

My version is the latest available from the store (4.1 build 29).

I've encountered a bug leading to the app crashing when trying to move multiple selected lines up (Alt+Up).

Conditions to reproduce:
The first line visible is not line 1.
Any document type except "Text" (I haven't tested all of them, but it's safe to assume, given that "Rich-text", "INI", "Markdown", "Lua", "Perl" are affected).

Basic steps to quickly reproduce:
Create or open a "Lua" document.
Pupolate the document and scroll down so that the first 20-30 lines are not visible (just to make sure).

Paste the following code:

Macro {
  end;
}

Select from "Macro" to the closing "}", then move selected lines up until the crash occurs.

My systems:
Windows 10x64Pro 2004 (19041.329)
Scaling is set to 175% (HD4000, latest available drivers) on one and to 144% (ancient GMA X3100, ancient drivers) on another, not sure if that's of any importance, but just in case.
Reproducible on both.
