Duplication bug when using Multiple Cursors

[VerAn1015]

Plugin information

• OS: Windows 10
• Templater version: 2.7.1
• Obsidian version: 1.6.7
• Templater settings: [Template folder location: "Templates/"]

Describe the bug
I have set up a custom highlight with a CSS snippet and use % tp.file.selection() % with it. It works fine when used normally. The problem is when using multiple cursors which Obsidian supports natively. It duplicates the most recent selected text when applying the template with templater. More info below.

Template file content: <mark class="red"><% tp.file.selection() %></mark>

<mark class="red">highlight 5</mark>
<mark class="red">highlight 5</mark>
<mark class="red">highlight 5</mark>
<mark class="red">highlight 5</mark>
<mark class="red">highlight 5</mark>

Expected behavior
Does not duplicate the highlighted text when using the template with multiple cursors.

<mark class="red">highlight 1</mark>
<mark class="red">highlight 2</mark>
<mark class="red">highlight 3</mark>
<mark class="red">highlight 4</mark>
<mark class="red">highlight 5</mark>
