Integration: panel snapshots for the assembled batch (#3525 × #2607, #2731, #3828)

#3525 asked for its snapshots to be regenerated once the batch is
assembled. Each change comes from a merged PR:
- panel_compare: the Show: Text / Visual filters (#2607).
- panel_layers: the Layer options button (#2731, Reset to Initial Visibility).
- panel_pages: the thumbnail size label, buttons and slider (#3828).
