<pre>Description:
LibreOffice ignores the replacement string when there is a regex positive
lookahead/lookbehind in the search field.
Steps to Reproduce:
1. Open a new ODT file in Writer
2. Type, for example, the following string : abbc
3. Open dialog Search & Replace
4. Regular expression Checked
5. Search for : (?<=a)b
6. Replace with : X (or whatever)
Actual Results:
LibreOffice find the first "b", but do not replace it. Replace is broken.
Expected Results:
Replace the first "b" with "X" : String should be now : aXbc
Reproducible: Always
User Profile Reset: No
Additional Info:
Step 5/6 can be reproduced with a positive lookahead :
Search for : b(?=c)
Replace with : X
Same thing : the string (last "b") is not replaced
-----------------------------
Interesting : negative lookahead/lookbehind work as expected.
Example : (?<!a)b or b(?!c)
-----------------------------
