Is new behavior not depended on Flags.Check(FEDITLINE_OVERTYPE)?

May be describe this feature in help in section @Editor in "Notes"?
For example (draft fantasy):

    4. If a vertical block is selected any text typing will replace the selected in all selected lines;
this behavior independent on #Ins# (Insert/Overtype) state.

    4. Если выбран вертикальный блок, любой набираемый текст заменит выделенное во всех выбранных строках;
это поведение не зависит от состояния #Ins# (Вставка/Замена).

The new behavior respects overtype and persistence blocks options. I've added a note in the help please check

good "quality of life" feature

but it works strange, when it is starting from an empty place or a column with no symbols before (265-269)
correct when starting from the same columns after existing symbols or replacing already existing (270-272)

it would be better to add spaces before it

fixed

@tempergate thanks for testing, fixed, please check.
Also 0-width vertical blocks are supported, select with alt+up/down and start typing, please give it a try as well.
