Preserve font properties after inserting a block widget

[Mgsy]

📝 Provide a description of the improvement

Currently, if we set any font property (e.g. size, family) and insert a block widget (e.g. a table), the font properties return to the default state, i.e. are removed. We handled that behavior for inline widgets - #14106 - so we might consider changing it for block widgets too.
