Hide tab bar if there is only one tab preference not working after toggling fullscreen

[starvingarden]

Description

Hide tab bar if there is only one tab preference is enabled. However, if I toggle fullscreen, then back to a regular window, the tab bar shows up. The only way to get it to go away is to close the terminal and reopen it

Expected behavior

Tab bar should remain hidden if there is only one tab no matter what I do

Actual behavior

Tab bar does not remain hidden after toggling fullscreen, then back to regular window

To Reproduce

In guake preferences, enable the "Hide tab bar if there is only one tab" checkbox. Then open guake terminal and toggle fullscreen, then toggle back to a regular window
