This is one of the default filters, I added scrolling= to the list of attributes to be checked, as I've found the value scrolling=auto or scrolling=no also prevents frame resizing.
[Patterns]
Name = "Allow for frame resizing"
Active = TRUE
Bounds = "<fram*>"
Limit = 1024
Match = "(#((frameborder|border|scrolling)=$AV(*)|noresize|"
"=$AV(0|no)$SET(#==1 )))+ 1 >"
Replace = "@1 border=1>"
[Edit: fixed a typo which caused erratic behaviour)
