>>>   My Info:   Win7_64, Nightly 48, 32bit, ID 20160313030418. DEFAULT THEME
STR (A),(B):
1. Open attached "testcase 1"
2. Hover mouse over the <select>'s dropmarker, hold left mouse button   [drop-down list will open]
3.A) Hover mouse over any visible option
3.B) Hover mouse over option the upper scroll button in scrollbar
4. Release left mouse button
5. Move mouse to urlbar and click in urlbar

STR (C),(D):
1. Open attached "testcase 1"
2. Click the <select>'s dropmarker   [drop-down list will open]
3.C) Hover mouse over any visible option. Click left mouse button.
3.D) Hover mouse over option the upper scroll button in scrollbar.
4. Do nothing
5. Move mouse to urlbar and click in urlbar

AR:
 (A,B)  Select has  :active  pseudoclass
 (C,D)  Select doesn't have  :active  pseudoclass

ER:
 Scenarios (A) and (C) should result in the same dropmarker state (e.g. not :active)
 Scenarios (B) and (D) should result in the same dropmarker state (e.g. not :active)

Note:
 I filed this bug separately from bug 1253979 just in case, because in bug 1253977 it became
 obvious that appearance of <select> may have nothing in common with pseudoclasses

Jim: this is not great but I think it's polish. Setting P1, can you set to '+'? I don't have permissions to set '+'.

Attachment: Clear the active state on mouseup

This patch clears the active state of the select on mouseup, and does so just after the mouseup event fires. This seems to work ok.

There is an obscure edgecase not fixed which I don't think really matters: Click and hold then keydown and press enter (that is select an item with the keyboard while holding the mouse). The active state will clear on popup close rather than mouseup.

This is still reproducible if I release the left mouse button over the scrollbar.
