We are not supporting this due to the complexity involved in switching integration managers. We still support custom ones under the hood, just not to the common user. A later sprint on integrations will consider re-adding the option alongside fixing the various bugs out there.
Fixes https://github.com/vector-im/riot-web/issues/10554
Issues fixed:
* Fields were not ~30px from the avatar (too much right margin)
* Tooltips overflowed the dialog on some resolutions
* SetIdServer didn't have an error state for making the field red
* Spacing between sections in Discovery was wrong (fixed by just removing the problematic n+2 selector - it didn't help anything)
As best as I can tell, the designs call for the IM URL to be the same size as
other subheadings. The font size in Zeplin doesn't match what is currently used
in Settings, so this likely caused confusion.
