Summary:

Currently, when selecting plain text and pasting a URL using Cmd/Ctrl + V, the selected text is hyperlinked instead of being replaced by the URL. It would enhance user experience if the paste action replaced the selected text with the URL directly.

Workarounds:

1. Delete or cut the text you wish to replace using Cmd/Ctrl + X, then paste the URL with Ctrl + V.
2. After the initial pasting, which creates a hyperlink, you can edit it to be inline as shown in the screenshot provided.
3. Use Cmd/Ctrl + Shift + V to paste the URL as plain text instead of an inline link.
4. Paste the URL twice to achieve the desired result.
