Gatsby develop only works with 5 pages

[williancozzi]

Description

When you run gatsby Develop, and open 5 new pages (in different tabs), everything is going to be normal and fast. But, the subsequent pages opened in new tabs will be suspended, like indefinitely. It will load the first five pages, and the other will be blank, they will work back just when you close one or more, of the previously 5 opened tabs. (edit: as related previously on #12225)

Steps to reproduce

1. Open Application
2. Click open in New Tab for a Unique Page
3. After doing step 2, 5 times, the other pages won’t load, but the first 5 will.

Expected result

Open, load and work with many new tabs as you want.

Actual result

New tabs will open but only first 5 are going to working fine, others won't open;
