Datapoint Singapore Bazaar Malay/Tightness of the link between the progressive marker and the verb

As far as my data is concerned, there are 3 progressive markers in Bazaar Malay:

(1) ada which literally means 'have'
(2) sedang
(3) masih and
(4) sendang
In my data, sedang as progressive marker occurs right before the verb and nothing can intervene.
