Re-render markers for which view element has been unbound during conversion

[scofalik]

There is a buggy scenario connected with markers, mapper and renaming elements:

1. Create a marker and map it to a view container element (for example table cell).
2. Rename that view container element (for example, set/unset table header).

Since the marker range has not changed, it won't be converted. But the renaming will remove the old view container element and insert a new one. This will lead to a situation when view marker representation is lost.
