Mouse-back button doesn't always work when viewing photos

[xy2z]

Steps to reproduce

(requires a mouse with a back button)

1. Upload a photo
2. View the photo
3. Move the cursor to the center of the photo horizontally
4. Click the back button on your mouse

Expected behaviour

Go back to the in history (to the files or gallery)

Actual behaviour

Nothing happens.

It only works when the cursor is to the left og right. So if there's only 1 photo in the folder, you can't use your mouse button at all.

Server configuration

Docker image 13.0.4-apache on Ubuntu 16.04 LTS

Move the cursor to the center of the photo horizontally

In the gallery?

@skjnldsv No when viewing the photo. Sorry, forgot that step.

Okay, I can reproduce there must be an event catcher that is too wide :)

It still doesn't work in the files app, could reproduce this on c.nc.c so it is still valid. But it works partly in the photos app. @skjnldsv will this need to be fixed in the server or viewer repository?

No clue
