Steps to reproduce
Open a few tabs in obsidian, then open a stand alone .md file (something that is not already in the Obsidian vault). It should replace the furthest right tab.
Did you read and follow the Troubleshooting Guide ? [Yes/No]
Expected result
I would expect that this would create a new tab in Obsidian rather than replacing an opened tab.
Actual result
Tabs are replaced by the stand alone .md file.
