create wallet spinner on panel doesn't show on second monitor

[LaurenWags]

Description

When joining Rewards from the panel, the 'Join Rewards' button should turn to 'Creating wallet' button with a spinner. This happens on my main laptop screen with both 0.68.132 (C76) and 0.68.134 (C77). However, if I do this on my second monitor, the button does not change when using 0.68.134.

Steps to Reproduce

1. Using a second monitor, launch a clean profile with 0.68.134
2. Click on panel
3. Click on Join Rewards

Actual result:

Button text does not change, spinner does not show:

Expected result:

Behaves as it does in 0.68.132:
