When same document is opened in multiple tabs and one tab is hidden, the other tab tries to restore the hidden tab scrolling position

[hsandt]

So multi-tab of same document support is quite good when all the tabs are visible on different panes, but say I have multiple tabs on some of my panes like this:

• Left pane: document A (visible)
• Right pane: document A, document B (visible) When I switch focus form Right to Left pane, the document A on the right will auto-scroll to the last position on the hidden document A from the Right pane.

Repro:

1. Create 2 dummy files A and B
2. Open tabs following this config:

• Left pane: document A (visible)
• Right pane: document A (visible), document B

3. In left pane doc A, scroll down to position X (you can keep it at the top)
4. In right pane doc A, scroll down to position Y (you can also select some text to make the bug more obvious)
5. In right pane, click on doc B to hide doc A. You now see A on the left at pos X, B on the right. Make sure right pane doc B is focused.
6. Focus left pane Expected: left pane doc A preserves scrolling position X Actual: left pane doc A scrolls to position Y (and highlights text if we selected some in step 4)

As a comparison I tried https://github.com/ludovicchabant/obsidian-remember-file-state which used not to support multi-tabs well, but it now supports them including hidden tabs properly.
