Two `':include'`s directly after one-another cause the second one to go missing

[Stausssi]

Description

First of all, thanks for this amazing project!

I use ':include' to include badges onto READMEs and I've observed that if I use

[](_badges/_foo.md ':include')
[](_badges/_bar.md ':include')

the contents of _badges/_bar.md (the second include) are not displayed and also not part of the HTML document.
Adding a newline in between the two includes fixes the issue, but adds a linebreak in the rendered document:

[](_badges/_foo.md ':include')

[](_badges/_bar.md ':include')

Replacing the ':include's with the actual contents, e.g.

[![Foo Badge](https://img.shields.io/badge/foo-badge-blue?style=for-the-badge)](/index.md)
[![Bar Badge](https://img.shields.io/badge/bar-badge-blue?style=for-the-badge)](/other_page.md)

displays both badges next to each other without a linebreak (desired behavior).

Expected behavior

The output should be the same when using ':include'.

Actual behavior

The second ':include' is discarded unless an explicit linebreak is added.

Steps to reproduce

1. Create two markdown files for the badges (one each)
2. Create another markdown file that ':include's them without a newline in between
3. Second badge is missing

Environment

Docsify version: 5.0.0-rc

Additional Information

• Bug still occurs when all/other plugins are disabled?

Thanks very much for reporting this issue @Stausssi!

Re: expected behavior, the second include should be displayed (great catch!) but in addition depending if two spaces are after the first line - for example, if two images are embedded with no line break inbetween and two spaces:

![Docsify Logo](https://raw.githubusercontent.com/docsifyjs/docsify/refs/heads/develop/docs/_media/icon.svg)  

Results are in Docsify:

Notice GitHub also displays the images stacked in this scenario.

For images next to each other, two spaces would not be included eol:

Results are in Docsify:

In addition to displaying the second include embed, this existing embedded image behavior (same line or new line) ideally would also be mirrored I think.

Is include files and images the same issue? @paulhibbitts

I also think this is expected behavior, since testing images in Marked behaves the same way.

TIL adding two spaces EOL change whether images are stacked or next to each other 🤯
Thanks for looking into this!

@sy-records The missing second include only, I included the image embed example as an existing behavior to ideally align the fix to (re: when to show side-by-side and when on a new line).
