Preface value not being applied

[hugo-id]

Steps to reproduce

• Open Firefox in a new profile
• Install Sidebery
• Try to set the preface value
• Doesn't apply

Actual behavior

I just can't seem to get the preface values to apply as expected

Expected behavior

The preface value is appended before the tab title.

I have done this on multiple distros, and devices, and this is the first time I've ever faced this issue.
