Can't seem to get index.md to reliably reroute to readme.md

[DexrnZacAttack]

Describe the bug

Tried these:

rewrites: {
    ':c0/readme.md': ':c0/index.md',
    ':c0/:c1/readme.md': ':c0/:c1/index.md',
    ':c0/:c1/:c2/readme.md': ':c0/:c1/:c2/index.md',
    ':c0/:c1/:c2/:c3/readme.md': ':c0/:c1/:c2/:c3/index.md',
    ':c0/:c1/:c2/:c3/:c4/readme.md': ':c0/:c1/:c2/:c3/:c4/index.md',
    ':c0/:c1/:c2/:c3/:c4/:c5/readme.md': ':c0/:c1/:c2/:c3/:c4/:c5/index.md',
    ':c0/:c1/:c2/:c3/:c4/:c5/:c6/readme.md': ':c0/:c1/:c2/:c3/:c4/:c5/:c6/index.md',
    ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/readme.md': ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/index.md',
    ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/:c8/readme.md': ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/:c8/index.md',
}

• /folder/index.html
• /folder/readme.html
• /folder/

  rewrites: {
    ':c0/readme.html': ':c0/index.html',
    ':c0/:c1/readme.html': ':c0/:c1/index.html',
    ':c0/:c1/:c2/readme.html': ':c0/:c1/:c2/index.html',
    ':c0/:c1/:c2/:c3/readme.html': ':c0/:c1/:c2/:c3/index.html',
    ':c0/:c1/:c2/:c3/:c4/readme.html': ':c0/:c1/:c2/:c3/:c4/index.html',
    ':c0/:c1/:c2/:c3/:c4/:c5/readme.html': ':c0/:c1/:c2/:c3/:c4/:c5/index.html',
    ':c0/:c1/:c2/:c3/:c4/:c5/:c6/readme.html': ':c0/:c1/:c2/:c3/:c4/:c5/:c6/index.html',
    ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/readme.html': ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/index.html',
    ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/:c8/readme.html': ':c0/:c1/:c2/:c3/:c4/:c5/:c6/:c7/:c8/index.html',
  },

• /folder/index.html
• /folder/readme.html
• /folder/

  rewrites: {
    '(.*)/readme.md': '(.*)/index.md'
  }

• /folder/index.html
• /folder/readme.html
• /folder/

  rewrites: {
    '(.*)/readme.html': '(.*)/index.html'
  }

• /folder/index.html
• /folder/readme.html
• /folder/

  rewrites: {
    '(.*)/readme': '(.*)/index'
  }

• /folder/index.html
• /folder/readme.html
• /folder/

Some work in docs:dev, but not when built.

Reproduction

Add the rewrites to the config.mts
Create a folder named folder, add readme.md to it, and try to go to all 3 of these URLs:

• localhost:5173/folder/
• localhost:5173/folder/index.html
• localhost:5173/folder/readme.html

Expected behavior

for /folder/index.md, /folder/readme.md, and /folder/ to lead to the same place.

Additional context

To me this seems like a bug but if it is not, and I'm doing it wrong, please redirect me to the correct place to get this answered/fixed.
Additionally I'm using vitepress-sidebar, which shows the Readme file and links to readme.html.

Validations

Apparently I wasn't on 1.4.3, but this does still happen after upgrading.
