Using Hashtag and Mention plugin causes browser hang

Hello,

So I was trying to add an Editor with by using both plugins Mention and Hashtag:

const mentionPlugin = createMentionPlugin({
    mentionPrefix: '@',
    entityMutability: 'IMMUTABLE'
});
const hashtagPlugin = createHashtagPlugin();
const { MentionSuggestions } = mentionPlugin;
const plugins = [hashtagPlugin,mentionPlugin];

<Editor
     editorState={ this.state.editorState }
     onChange={this.onChange}
     plugins={plugins}
      ref="editor"
/>
 <MentionSuggestions
       onSearchChange={ this.onSearchChange }
         suggestions={ this.state.suggestions }
/>

• Normal behavior if you don’t write hashtag at the beginning of line :

• Browser will hang if you try to write hashtag at the beginning of line/text

I also has same issues with #168 as well.
