Issue Summary

With the rollout of the Custom font sizing for Confluence whiteboards, while you can adjust the font size by clicking on the Tt on the toolbar, for a sticky note text for example, sometimes if you adjust the font size, and try to resize the sticky note by clicking on it to select it, and using the arrows to resize it, the sticky note suddenly becomes really bigger than expected (E.g: Resizes it to be a size 50 font size, probably 50 x 50 sticky note size) and the font size instead of keeping the for example "50 font size", changes the number to 2597950 after the weird resize. It is an intermittent behavior.

Steps to Reproduce

1. Create a new whitboard
2. Add some sticky notes
3. Select the sticky note, change the font size at Tt on the toolbar
4. Select the sticky note and try to resize it
5. Do it for all sticky notes, until you can reproduce the issue, create more as needed.

Expected Results

Resize of the sticky notes are within the specified size chosen after the "drag and drop" for resizing

Actual Results

If you adjust the font size before resizing the sticky note, it becomes unexpectedly large al of sudden and not proportional to the whiteboard you were working on

Workaround

Adjust size of sticky note before changing the text font size.
