Compare the two attached images from a file download in 62.0.3186.0. On the second line is the progress string.

In English, the string has, in order:
1) progress in bytes/total
2) estimated time remaining

In Hebrew, the string has, in order:
1) estimated time remaining
2) progress in bytes/total

We're building the string incorrectly. In fact, take a look at the string. Do you see the little tick mark next to the beginning of the string in the Hebrew version? That should be at the end, which shows that we're breaking the RTL algorithm.
