Download File Link Wrong Extension / Name

Summary

Since 11.2 you are able to download a single file via the downloade-button. The URL behind that button seems to be https://<URL>/MyProject/raw/master/Test.hex?inline=false. If I use this link directly in a browser the file does not get downloaded correctly.

The content matches the original file, but the name and/or extension gets changed depending on the extension.

• ".hex" -> extension gets changed to ".txt"
• ".eds" -> name gets changed by name of the repository and extension gets changed to ".txt"
• ".h" -> everything ok (name and extension matches original from repository)

Steps to reproduce

1. Have a project with a Hex-File, an EDS-File and a Header-File.
2. Move to the directory of the files.
3. Open the files.
4. Click on Download-This-File-Button-> everything OK
5. Right-click on the button and select "Copy Link"
6. Paste this link in a browser (should look like https://<URL>/MyProject/raw/master/Test.hex?inline=false)
7. Press Enter

• 'test.h' -> gets downloaded as 'test.h'
• 'test.hex' -> gets downloaded as 'test.txt'
• 'test.eds' -> gets downloaded as 'test.txt'

What is the current bug behavior?

Name and/or extension gets changed by downloading it via the link.
