Is your feature request related to a usage problem (not a bug)? Please describe.

1. The sidebar looks horrendous in compact mode. The text that is displayed next to the icons in large mode is just displayed smaller below the icons in compact mode. This reduces space for the icons which in turn leads to small icons with hardly readable text. This is especially bad in some languages like German

Describe the bug
The Post.mentions attribute (list) includes potential email addresses.

To Reproduce
I used Instaloader as Python module.

Expected behavior
Say that someone's email i_am_me@outlook.com appears in the caption. Instaloader will currently list @outlook.com as a mention, which is obviously wrong.

Using the Web interface in Chrome (and in the Android app), and noticed this hanging out in the console:

[Deprecation] document.registerElement is deprecated and will be removed in M73, around March 2019. Please use window.customElements.define instead. See https://www.chromestatus.com/features/4642138092470272 for more details.
