Search breaks after visiting a markdown file link with line

Type: Bug

1. Create a 2 multi-line files (file1, file2), with whatever content, lorem ipsum
2. Create an .md file which points to the previous file refererencing one specific line. e.g. file1#100
3. Preview this .md file and click on the link to navigate to the line 100
4. Go to the search tab on the left and search for content within file2 (it also happens looking for content in file1 but less evident)
5. The search will never finish.
