Attachment: testcase 1 - [e10s] Cursor in input, textarea is displayed wrong.htm

>>>   My Info:   Win7_64, Nightly 46, 32bit, ID 20151217030207
STR:
1.   Open attached "testcase 1" (or "data:" url in the form above)
2.   Select string "first" in <input> using mouse
3.   Hover mouse cursor over selected text
4.   Hold left mouse button (don't release it yet)
5.   Move mouse cursor between "X" and "Y"
6.A) Press Escape, release left mouse button
6.B) Hover mouse cursor over selected string again, release left mouse button
7.   Select string "ZT" in <input> using mouse
8.   Select string "KL" in <textarea> using mouse

Result (I only describing what happens with the cursor in <input>):       
 (A) After Step 6 cursor is displayed between "X" and "Y". Cursor isn't blinking
     After Step 8 cursor starts blinking

 (B) After Step 6 cursor isn't displayed
     After Step 8 cursor appears between "_" and "X" and it's already blinking

Expectations: 
 Cursor shouldn't be displayed after Step 6, 7 and 8. Try non-e10s to see expected behavior in details

Did you mean bug 1231944? This bug is about text cursor in <input> / <textarea> elements,
not about mouse pointer. And the try build still exposet this bug.

That's probably very bad sentence in English... I meant that the bug isn't fixed in the try build
