Links to non-inline-image attachments broken

[jrarmstro]

What happened?

When attempting to link to an attachment that is not an inline image, the resulting link is incorrect.

What did you expect to happen?

A link to an Attachment should point to the attachment correctly.

How can we reproduce the behavior you experienced?

Run mark for the following file

<!-- Title: Example -->
<!-- Attachment: examples/example.yaml -->

# Test

[Example](examples/example.yaml)

$ mark --base-url "https://redacted.atlassian.net/wiki" --space "~123456789" -f ./README.md
2025-11-12 14:14:50.291 INFO  processing README.md
2025-11-12 14:14:51.537 INFO  page will be stored under path: Overview > Example

https://redacted.atlassian.net/wiki/spaces/~123456789/pages/987654321/Example

The resulting link to Example is actually a link to some other page in the space, which we can also see in the dry run output:

$ mark --dry-run --base-url "https://redacted.atlassian.net/wiki" --space "~123456789" -f ./README.md
2025-11-12 14:16:21.519 INFO  processing README.md
2025-11-12 14:16:23.516 INFO  page will be stored under path: Overview > Example
<h1 id="Test">Test</h1>
<p><a href="/wiki/spaces/~123456789/overview">Example</a></p>

This example is in my "personal" space in Confluence, but the same behaviour is observed in other spaces.

Further Information (please complete the following information)

• Mark Version: v15.0.0
• Confluence Hosting: Cloud
• Environment specific Information: macOS

Additional context

When link.go resolves page metadata the resolved linkMeta.Title appears to be empty when I added some additional debugging:

fmt.Println("extracted link metadata:", "space=", linkMeta.Space, "title=", linkMeta.Title)

> extracted link metadata: space= [redacted] title= 

Preventing link.go from trying to getConfluenceLink when linkMeta.Title == "" seems to resolve the problem:

		if linkMeta.Title == "" {
			return "", nil
		}

Dry run leaves the link in place (rather than linking to some unrelated page in the space):

$ mark --dry-run --base-url "https://redacted.atlassian.net/wiki" --space "~123456789" -f ./README.md
2025-11-12 14:24:05.939 INFO  processing README.md
2025-11-12 14:24:07.311 INFO  page will be stored under path: Overview > Example
<h1 id="Test">Test</h1>
<p><a href="examples/example.yaml">Example</a></p>

And a non-dry-run provides the expected link to the attachment.
