For some users, names of channels with unread messages are incorrectly rendered in the side bar.
Steps to reproduce
Observed on Linux and macOS High Sierra with desktop client version 4.1.2 and also earlier
Other required conditions unknown. Seems to have only started since upgrading from 5.2 to 5.4.
Name of unread channel is bold
Name of unread channel appears to show both bold and non-bold text superposed.
Some examples attached (partially blacked out for privacy) from different themes. We have seen this for all types of channel.
