hunspell to handle common english verbs contractions for -ing

Question

Hunspell does not handle by defaults common English Verb contractions of -ing like goin, givin, doin, etc. These verb contractions it seems not to be handled. Let's take an example

I'm going to surfin' and livin' on my own and maybe givin' up

This will be the hunspell correct, suggestions, analysis (morphological) for this sentence:

so for contractions like givin the correct flag is false and there are some suggestions, among them the -ing form giving. For some reason, the morphological analysis is not present. So how to add support for English verb forms of verbs followed by -ing in order to be considered as correct terms? Shall be added some rules fo the affix dictionary for English?
