Observed

Using the feature "Jump to Commit SHA-1" with whitespaces like so (without quotation marks):
  
" 18eb4c4c3ce"
"18eb4c4c3ce "

...will result in the appearance of a spinner blocking the "Jump to:" drop down field (disappears only after clicking onto another branch) and does not select the desired commit in the tree view.

Expected

Whitespaces are omitted from the hash and the desired commit is selected in the tree view
