I can reproduce the issue both at work and at home.
Make sure you do not set the search footer visible property to true from the ide before running the project.
Setup at work and home are differents so I dont think it's computer / software specific.
What I do is make a new VCL app. Drop a grid and button. I add an onclick event for the button to toggle the search footer and it doesn't work when I spam click the button.
I can confirm I have the most recent Component Pack Version.
I'll include the dfm definition for the grid if it can be of any help (it's all default properties):
