Selection doesn't drag vertically when text is too long horizontally

[nooblyf]

Describe the issue

I've noticed this happening only when the text is both vertically and horizontally scrollable

When i select the text and move the mouse up outside the code block the selection should be dragging the selection up? like it does when i move outside horizontally at 00:18

I don't know if i'm explaining this right, here's a screen recording
