Even Editorial is not Error-Free Grammatically

Having been given this generous leeway, it is hoped that PTAs will take heed of the options suggested by Alimuddin.

The above is taken from a newspaper editorial (January 3).

We can see that 'Having been given this generous leeway' is modifying the 'it'. What is this 'it' then? In fact, the said modifier is modifying PTAs. That is to say PTAs are having the generous leeway.

Hence, the sentence is question should have been 'Having been given this generous leeway, PTAs, it is hoped, will take heed of the options suggested by Alimuddin' to be grammatically correct.
