I am having the same issue: I tried to add an SVG with the viewBox attribute, but am not able to save it because of the »error«.

  • Version set to 5.5.2

Can anyone take a look at this? Even I am having the same problem as @FlorianBrinkmann with using SVG code.

Same issue here. Cannot save an HTML widget with attribute "viewBox" (WP 5.7).
Error: The attribute name of [ viewBox ] must be in lowercase.

  • Keywords has-patch added
  • Version changed from 5.5.2 to 4.9

47976.diff simply disables the error for uppercase letters in attributes.

If the error is important to keep for most situations, the attr-lowercase rule could have an array of specific exceptions instead:

['viewBox', 'DATA-HREF']
