Upgraded and now insert image isn't working

Before I upgraded to the newest version of WordPress when I inserted an image into a post and selected an alignment it would wrap the text around the image. The code would look similar to the code below. I changed the source and title for this example.

<img class="aligncenter size-full wp-image-6563" style="float: left; margin-left: 10px; margin-right: 10px;" title="sample" alt="" src="https://www.samplebefore.com" width="125" height="146" />

After I upgraded and insert an image into a post it no longer includes the float attribute. It now looks like the code below. Did something change? I can insert it by hand but it’s annoying. Also it had been a while since I upgraded.

<img class="alignleft wp-image-9237" style="margin-left: 10px; margin-right: 10px;" alt="sample" src="https://www.sampleafter.com" width="150" height="150" />
