Hi Samuel,
I did play around with image size, even change the image size to 50px x 50px still not resolved the issue and wordpress 5.0.2 failed to display the 2 column blocks correctly.
-See examples here of here image resizing to 150px and 50px fails: https://precisionphotographyballito.co.za/column-issue-page/
This work perfectly before I updated to twenty seventeen ver 1.9 (previous was ver. 1.7) wordpress ver 5.0.2 (previous WordPress 4.9.9 & Gutenberg 4.4.0)
every single column block on my site where i have used an image is not displaying columns correctly.
I’m i the only one who has reported this issue?
