Subject: [PATCH] EditTextObjectImpl copy ctor doesn't exactly copy

and this is apparently relied on, so eliding the copy gives unexpected

|
f0c99f1 |
results.

EditTextObjectImpl::Clone returns a copy of *this, but the
|
|
|
f0c99f1 |
EditTextObjectImpl copy ctor explicitly does not copy the "PortionInfo"
|
|
|
f0c99f1 |
member, so in:

ofz#23492 the only user of this ctor throws away the original of the clone
|
|
|
f0c99f1 |
|
|
|
f0c99f1 |
so we can take ownership of the original instead
|
|
|
f0c99f1 |
|
|
|
f0c99f1 |
where the copy was optimized away we want from a state where there was a
|
|
|
f0c99f1 |
new EditTextObjectImpl with an empty PortionInfo member to one where the
|
|
|
f0c99f1 |
PortionInfo of the EditTextObjectImpl was retained.
|
|
|
f0c99f1 |
|
|
|
f0c99f1 |
So explicitly clear this unwanted info.

It's very hard to make rational judgements about code if a copy behaves
|
|
|
f0c99f1 |
differently than the orignal :-(
