Describe the bug
After add some blocks and delete them, I found the memory usage is extremely high.
To Reproduce
Steps to reproduce the behavior:
- Visit blockly demo in safari (my safari version is 10.15.4)
- open safari's devtool , choose timeline, and start record.
- add some blocks and then delete them casually.
Expected behavior
Before step3, the memory usage is 70M+.
After step3, the memory usage is 200M+, even though the workspace is still empty.
Screenshots
Desktop:
- OS: mac os
- Browser: safari
- Version: 10.15.4
Additional context
The memory usage increased in PAGE.
If we use it in mobile device that memory capacity is pretty small, It may cause some performance problem.
