b-form-file error messages onMouseMove

See original GitHub issue

Using b-form-file as in the example:

<b-form-file v-model="file"></b-form-file>
<br> Selected file: {{file && file.name}}

  data: {
    file: null,
    …

Results in console error messages in Chrome 58 (but not Firefox 53) when the mouse is moved over the file-selector area:

cperacontent.js:641 Uncaught TypeError: Cannot read property 'startContainer' of null
    at Object._onMouseMove (cperacontent.js:641)
    at onMouseMove (cperacontent.js:636)

In fact, you can see these errors on the https://bootstrap-vue.github.io/docs/components/form-file/ page itself, when moving the mouse over the example.

FYI, tracked down what this is related to: a Chrome plugin, Perapera Chinese Popup Dictionary, which displays Chinese dictionary info when you hover over a Chinese character. When I restarted Chrome, the plugin defaulted to disabled. After enabling the plugin again, the strange interaction occurred again and the console messages reappeared when moving the mouse over the <b-form-file> component. Interestingly, this interaction doesn’t occur when hovering over other bootstrap-vue components in my test app, including <b-button>.
