Description

When rendering scripts in PartialPageResponse, an AppendingStringBuilder with initial capacity 1024 is created. This buffer is then written to a StringResponse that uses a buffer with an initial capacity of 128 causing unnecessary allocations.

We should create the StringResponse with enough capacity to hold the scripts.
