Steps to reproduce
- Open two different notes in adjacent panes. (e.g. by opening the help vault and unlinking the panes)
- In one pane, create a large amount of text that includes a ```-fenced code block (or navigate to the “Format Your Notes” page in the help vault)
- Ensure the pane is in preview mode, active, and scroll to the bottom of the note
- Drag the pane so it is before or after the other pane, keeping the current split direction
Expected result
The moved pane should continue to be displayed (preferably at the same scroll position). If it was the active pane, it should remain active.
Actual result
The moved pane is partly or fully blank, and no longer active, with the scrollbar positioned at the top. Scrolling it restores the missing content.
Environment
- Operating system: Windows
- Obsidian version: 0.10.9
Additional information
It seems to only be a problem when there’s a fenced code block in the page. The amount of content that disappears seems dependent on how far down you scroll. It doesn’t seem to happen if the pane changes parents (i.e. you move from a horizontal split to a vertical one or vice versa, or drag out of the current parent altogether).
It appears the reason it works when the split direction is changed, is because the pane is being resized and triggering an update of the virtual display. Calling the moved leaf’s onResize() method works around the problem, but it’s not clear why it’s a problem in the first place, i.e.
- Why is the scroll repositioning in the first place?
- What does having fenced code have to do with it?
Answering those questions is above my current level of reverse-engineering skill.
