Unexpected behavior when cycling through tabs while opening a file that takes a long time to display

[zyoshoka]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.98.0-insider (e95380d)
• OS Version: macOS Sequoia 15.3

Steps to Reproduce:

1. Edit keybinding.json like this:

[
  {
    "key": "ctrl+tab",
    "command": "workbench.action.nextEditor"
  },
  {
    "key": "ctrl+shift+tab",
    "command": "workbench.action.previousEditor"
  },
]

2. Then open a jpg file and other arbitrary files.
3. Keep switching tabs with ctrl+tab or ctrl+shift+tab.

This bug is not limited to JPG files. An extension that displays PDF files also reproduced this problem: James-Yu/LaTeX-Workshop#4537

In this video, you can see several times how a tab moves twice with a single press of the shortcut key.¹

Could you check if this reproduces when you disable all extensions? I'm not able to reproduce this behaviour.

[zyoshoka]

It was reproducible even after disabling all extensions.

Perhaps splitting the editor may be necessary to reproduce.

I did try splitting the editor and used a very large image
