Comment (by afercia):

 Investigating a bit on the original issue, I think it's also something
 related to timing. There are two small pieces of JavaScript involved
 there: in the Add New post screen, the first JS puts focus on the title
 field, and the second removes the "placeholder" (actually it's the label).
 One of the JS is inline in the page, the other one is in an enqueued
 script. I think this leads to different behaviors, depending on the
 browser speed in parsing the page and JS and then run the related JS
 functions. Hardware can play a role too. This is what I see dumping some
 debugging text in the console when the two functions run:
