LO Calc:

Using File->Export to export a Bubble Chart to PNG or JPG loses transparency of bubbles.

Steps to Reproduce:
1.Create Bubble Chart with bubbles with transparent areas.
2.Select Bubble Chart
3.File->Export to PNG or JPG


Actual Results:
4.The image has solid bubbles without transparency.

Expected Results:

Reproducible: Always


User Profile Reset: Yes

Additional Info:
This is how it should look like (and did in version 6):

The solid bubbles in version 7 look fairly ugly in comparison.
