(Web, Safari) Copying and pasting line with colon and no leading space results in URL encoding of pasted text

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

• VS Code Version: Web
• OS Version: iPadOS 18.1 (Safari)

VSCode Web on iPadOS/Safari appears to be erroneously encoding certain copied text as a URL.

So copying this string of text from a VSCode Web file: foo: bar

And pasting it into another VSCode web file will result in: foo:%20bar

This is only the case if there isn’t a space before the colon anywhere on the line. So, foo: bar and foo bar: baz both copy and paste normally.

This also only happens within VSCode web. So, copying foo: bar from an external app and pasting it into VSCode Web or copying foo: bar from VSCode web into another app both work fine.

I have not been able to reproduce this on VSCode Web on Mac or Windows.

Steps to Reproduce:

1. On iPadOS on Safari, open a new file on VSCode Web (or Github Codespaces)
2. Write text foo: bar
3. Copy to clipboard, where the first character of selection is NOT whitespace
4. Paste into same file.
