f7 icons missing in 3.16.3-beta

[hemagi]

Actual behaviour

Since 3.16.3-beta the f7 icons are no longer shown in Buttongrids, e.g. staticIcon=f7:arrowtriangle_up_fill

Expected behaviour

The icons should be shown like in the stable app or the betas before

Steps to reproduce

Use a test sitemap and a configuration like

Buttongrid item=Lam_EZ_pos label="Esszimmer [Lamellen %d %%]" staticIcon="blinds" {
    Button item=Jal_EZ label="auf" staticIcon=f7:arrowtriangle_up_fill row=1 column=1 stateless click=UP
    Button item=Jal_EZ label="ab" staticIcon=f7:arrowtriangle_down_fill row=1 column=2 stateless click=DOWN
}

Can you reproduce the issue in demo mode?
