Backport fix for bug 1590538

Mozilla landed a fix for our legacy/trac#31764 (moved). We should backport their fix and remove our workaround

We tested by:

1. Backing out Richard's original patch for legacy/trac#31764 (moved) (commit 59d89229 on tor-browser-68.4.1esr-9.5-1).
2. Building on Linux and then confirming that the original bug did occur.
3. Applying the patch from comment:5 (backport of Mozilla's fix).
4. Rebuilding and verifying that the original problem has disappeared again.

We also need to remember to drop Richard's original patch when we merge this one.

Thanks. I cherry-picked the patch to tor-browser-68.4.1esr-9.5-1 as commit d361b0b2c8e51cec5088233006be152c340b6553, and reverted the previous fix with commit 45677fd3bc4fd9b69216bb25efadcbac3026672f.
