Short Description: On the test steps fields, the atlassian's editor seems to automatically increase the image size once the user clicks on the image and it does not let resize the image back to its original size.

Steps to Reproduce:

1 - Create a manual test step.

2 - Past a small image in one of the steps.

3 - Now edit the step and click on the image (or in the side bars that appear on both sides of the image). It seems that the size of the image is automatically increased.

4 - Now, try to reduce the size of the image.

Actual Results: the editor does not seem to allow the user to resize the image back to its orginal size (when it was pasted).

Expected Results: the user should be able to redice the size of the image to its original size.
