Ignore in contextual anchors

[Reza]

Hi
First

@GeorgSeifert

for your second question. You can add lookup flags before the context, delimiting it with a ;.

lookupflag IgnoreMarks; [@Re @Ve]

not working
Also, creating a list of glyphs to ignore would be great.
Second
In ligature (Arabic script) *bottom_1 or like this not working
How can I use contextual anchor in ligature?
