As for version 69.0.3497.100 (Official Build) (64-bit) in Ubuntu is still a bug.
As a workaround you can start adding: //` to the end of lines containing templated strings, which fixes the formatting in the chrome sources tab.
Here some examples of my working jsx code.
In component props:
<Field
name={`${fields.name}[${index}].comments`}// `
component="input"
type="text"
/>
As a child element:
<label>
{`${t('Condone')} `}{/* ` */}
</label>
In a statement:
switch (DEBTTYPE) {
case DEBTTYPE_MACHINE_PRODUCT:
id = `machine_product_difference_row_${row.id_productdebt}`;// `
break;
....
I really hope that they can fix this issue as fast as possible.
