Test: wrapping using the DOM

[alexdima]

Test for #2654

• Any @kieferrm
• Any @sana-ajani

Complexity: 3

There is a new setting, editor.wrappingAlgorithm that can be configured to dom (as opposed to the default monospace), in which case the editor will delegate wrapping points computation to the DOM. This will be slow/laggy for large files.

Please check that using "editor.wrappingAlgorithm": "dom":

• characters outside Latin / emojis wrap better now when using a monospace font
• using non-monospace fonts leads to correct wrapping
• changing the wrapping algorithm will rerun the wrapping points computation
• please also try some RTL text as well
• please also leave any feedback about the setting name / setting value / setting description if you have ideas.

Thank you!

Insiders version:

The word wrapping just totally stop working while turn on "editor.wrappingAlgorithm": "dom":

The font family Simsun's space chararacter is recogonized as fullwidth which should be halfwidth, this leads to the wrong wrapping point at Couri[e]r. Vscode stable 1.41.1 also got this issue.

After turn on dom option, line7 and line8 just stop wrapping while line3 is still wrapping with above issue.

As a contrast, the above issues are all gone while font family set to Consolas:

But wrapping still not work for line7 and line8:

settings.json

{
    //"editor.wrappingAlgorithm": "dom",
    "editor.fontFamily": "Simsun, Consolas, 'Courier New', monospace",
//12345678
    "editor.fontSize": 20
}

@qaqz111 This now works correctly for me after the changes for #89571

Please open a new issue if you observe something is off. Thank you!
