Pasting markdown style link with label makes nested link

[kcarnold]

What happened?

I regularly use the feature of copying a URL, selecting some text in Logseq, and pasting to link to that text. But sometimes I copy some text instead. When I paste I expect it to replace the highlighted text with what was in the clipboard. But instead it tries to make a link, which makes at best a broken link and at worst some malformed Markdown.

This could be viewed as just "user error" since in every case I can think of I could have done something different, but I still stumble on it often, and it should be not too hard to check that the thing you're pasting is actually a valid link target. (Some non-URLs could be link targets, like asset file paths, so maybe this is a bit tricky.)

Reproduce the Bug

1. Type some text.
2. Copy some other text that's NOT a URL
3. Select some of the text you typed.
4. Paste (ctrl/command-V)

Expected Behavior

The selected text is replaced by the text on the clipboard, since it wasn't a valid link target.

@kcarnold Can you provide the item you pasted?

Specific example: first I paste https://github.com/d3/d3-sankey, then I go back and use my bookmarklet to copy [d3/d3-sankey: Visualize flow between nodes in a directed acyclic network.](https://github.com/d3/d3-sankey). I select what I'd originally pasted and press Paste again. Result: [https://github.com/d3/d3-sankey]([d3/d3-sankey: Visualize flow between nodes in a directed acyclic network.](https://github.com/d3/d3-sankey))
