Bug 146695 – REGRESSION (r183133-r183138): Secondary clicking in whitespace selects preceding word

• Status: RESOLVED
• Resolution: FIXED
• Component: WebCore Misc.

[Brent Fulgham]

While resolving Bug 143958 I introduced a problem with using the context menu to paste content into an editable fields. With the new changes, if you right-clicked in a whitespace area with the intention of pasting content, the new selection logic will hop over the whitespace and grab the preceding word.

To fix this, we should use the original behavior with editable fields so that we can leave our insertion point where it is when pasting.

Can we get a layout test for both modes?

IIRC in previous tests, I used <spans> to give JS something to target so that you could get rid of the 200 here and just read offsets/clientRects/whatever (and use the center).

Might be less fragile.

EWS shows that my test *is* fragile, so I will try this!

Looks like the test is failing on the bot?

Can we extract a helper function to do this?
It's not great to repeat it here and in editableTest

window.getSelection() is never undefined.

Why don't we just do:
shouldBe("getSelection().toString().trim()", '"New York, New York"') instead?

We should check this condition in onLoad() function instead.

It's wrong to have PASS output after TEST COMPLETE. Please use jsTestIsAsync and finishJSTest() instead of testRunner methods.

This is also unneeded, js-test-pre does that automatically.

This looks suspect. What is the operation that we need to wait for after loading?

[Brent Fulgham]

The timeouts in my test case are caused by Bug 146836.

Do you still need this now that contextClick doesn't actually pop a context menu?

You're right. I'll take this out.
