Merge #5145

5145: Put assert for text containers after printing all non empty text cont… r=def- a=Jupeyy

…ainers

No idea how to reproduce this, gerdoe also has this and send me his config, but no chance
Tho since the text container index is so high, i kinda assume its not the only non cleared text container.
Maybe estimating the character count based on the quads used can also help, since then i can see what text is potentially the cause
