Link to another note in the same book opens in a new tab in Chrome.

Is this a hackmd.io issue?

• Yes, the bug happens on https://hackmd.io

What's the problem

Current behaviour

1. Go to https://hackmd.io/@benabraham/book-example/
2. Open any link on the right side: link in “Go to Page B” etc.
3. Link opens in a new tab (most of the time).

Sources

• Book https://hackmd.io/0HWwfBvSR_eeA4f95qteZA
• Page A: https://hackmd.io/bC65cLJtT4iRtmCLxbIPKg
• Page B: https://hackmd.io/qoN4Ee9NSY-r9Adv4avV3g
• Page C: https://hackmd.io/uq8RHC3gQfWAb4QvqoUakQ

Expected behaviour

I expect note to open in the same tab and in the right pane of the book: the same it works in both the latest Firefox and Edge 18 because links have exactly the same URL as in the „book“.

Environment

I use HackMD on Desktop

• OS: Windows 10
• Browser: Chrome 64-bit
• Browser Version: 80.0.3987.149

This behavior is also visible in:

• OS: Linux Mint 19.3
• Browser: Chromium
• Browser Version: 80

and mobile

• OS: Android 9
• Browser: Chrome
• Browser Version: 80

Additional context

I tested it using a clean user profile (everything is default, no extensions except Google's default for offline Docs use).

I suspect this behavior (always open links in a new tab, except links in a book frame) is the default/expected. See "Does clicking on a link always require a new tab?" #110 .

It should open exactly the same links inside the right pane: see https://github.com/hackmdio/codimd/issues/658

If not, it would be weird that it works in every other browser except Chrome. And in Chrome it seems to work randomly from time to time…

[reagle]

You are correct, no no tabs on Firefox. My theory at the time is that Firefox ignores _target directives, but I don't know...

No, it works. Check yourself. https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/target

To me it seems that the JavaScript that changes that behavior has a bug in Chrome.
