tdf#124983 In calc make printable page borders initially visible
If option "LibreOfficeDev Calc/View/Page breaks"
is enabled, breaks should be visible. But if the document
is opened the first time or a tab is opened the first time,
the breaks are not calculated yet and therefore not visible.
To avoid calculations during the load of the document, a
timer will be triggered to calculate the breaks after loading
is finished.
