[BUG] Drag error: Cannot read properties of null (reading 'left')

Describe the bug

I have a document where drag reordering is not working for some reason (it always works in other docs at the same time). I'm not sure what is so unique about this doc, but when I open the dev console, I see this stacktrace:

Uncaught TypeError: Cannot read properties of null (reading 'left')
    at DragAndDropState.calculateLeftPadding (plugin:obsidian-outliner:1341:56)
    at new DragAndDropState (plugin:obsidian-outliner:1257:14)
    at DragAndDrop.startDragging (plugin:obsidian-outliner:1151:23)
    at DragAndDrop.handleMouseMove (plugin:obsidian-outliner:1068:22)

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'

Same for me here, drag & drop not working at all.

• OS: macOS
• Obsidian Version: 1.4.1
• Plugin Version: 4.7.1

Uncaught TypeError: Cannot read properties of null (reading 'left')
    at DragAndDropState.calculateLeftPadding (DragAndDrop.ts:434:52)
    at new DragAndDropState (DragAndDrop.ts:327:10)
    at DragAndDrop.startDragging (DragAndDrop.ts:161:19)
    at DragAndDrop.handleMouseMove (DragAndDrop.ts:131:12)

and there's also vertical line error from time to time

    at VerticalLinesPluginValue.recursive (VerticalLines.ts:173:35)
    at VerticalLinesPluginValue.calculate (VerticalLines.ts:110:16)
